“The potential applications of quantum computing are vast and varied, from improving drug discovery to revolutionizing cryptography. But with limited availability, it can be difficult to fully realize the impact of this technology. That’s why keeping up with the latest updates on the current state of quantum computing is crucial.” -Unknown
In this blog post, we will explore the current availability of quantum computers, including the most recent developments and breakthroughs in the field. Whether you’re an expert in technology or simply curious about the future of computing, discovering the latest updates on quantum computers is an essential step towards understanding the impact that this technology could have on our world.
Quantum Computers Are Not Commercially Available Yet
Despite the hype and excitement surrounding quantum computing, it’s important to note that commercial quantum computers are not yet available. While there have been some demonstrations of rudimentary quantum computers with a few dozen qubits (quantum bits), these machines are not yet powerful enough to solve practical problems or outperform classical computers in most tasks.
This doesn’t mean that progress isn’t being made in the field of quantum computing. Researchers around the world are working hard to develop larger and more reliable quantum processors, as well as new algorithms and software for programming them.
The Current State of Quantum Computing
As of 2021, the largest publicly known quantum computer is Google’s Sycamore processor, which has 53 qubits. Other leading companies and research institutions such as IBM, Intel, Microsoft, Amazon, and Rigetti are also working on developing their own quantum computing systems, each with their unique approaches and strategies.
These companies offer cloud-based access to their quantum machines through dedicated platforms, such as IBM Q Experience and Microsoft Azure Quantum, allowing researchers and developers to experiment with quantum algorithms and start building applications for future quantum computers.
But despite the impressive technical achievements, current quantum computers are still very limited in their capabilities. One significant challenge is maintaining the delicate quantum state of the qubits, which can easily become disturbed by environmental noise and other external factors.
Another challenge is scalability – while adding more qubits increases the processing power exponentially, it also adds new layers of complexity to the system and requires novel techniques to achieve error correction and fault-tolerance.
The Potential of Quantum Computers
So why all the fuss about quantum computers if they aren’t even commercially available yet? The answer lies in their potential to revolutionize computing as we know it.
Quantum computers have the ability to perform calculations that are practically impossible for classical computers. By exploiting quantum phenomena such as superposition and entanglement, quantum computers can process information exponentially faster than classical computers on certain problems, including optimization, cryptography, and simulation of complex systems like chemical reactions or biological processes.
This could bring game-changing advances across various fields, from finance and logistics to drug discovery and climate modeling, by providing solutions that were previously beyond reach.
The Challenges of Developing Quantum Computers
Despite the vast potential of quantum computers, developing them is an incredibly difficult task that requires years of research and experimentation. One key hurdle is finding ways to scale up the number of qubits while maintaining coherence and minimizing errors – a problem known as quantum decoherence.
To overcome this challenge, researchers are exploring various approaches, such as using different materials for qubit fabrication, improving cryogenic cooling techniques, or developing new error-correction codes that can protect against noise and other disturbances.
Besides technical challenges, there are also economic and regulatory hurdles to commercializing quantum computers. Building these machines requires a significant investment in R&D, specialized infrastructure, and highly-skilled talent, which may not always be feasible or profitable for companies operating under short-term market pressures.
Moreover, with the growing interest in quantum technologies, governments around the world are starting to invest heavily in quantum research and development, creating a global race for quantum supremacy that raises political and security concerns about technological dominance.
The Future of Quantum Computing
Despite all the challenges, many experts believe that quantum computers will become a reality in the next decade or so, ushering in a new era of computing and transforming society in profound ways.
Some predict that quantum computers will primarily be used as co-processors, accelerating specific tasks for classical computers rather than replacing them entirely. Others envision a world where quantum computers can run entire applications or solve optimization problems in real-time, revolutionizing fields like finance and logistics.
“Quantum computing has the potential to transform industries from healthcare and transport to energy and finance,” said Antonio Neri, President and CEO of Hewlett Packard Enterprise. “It’s an area we expect to grow significantly over the coming years.”
Regardless of how quickly quantum computers become commercially available, it’s clear that they are poised to change our understanding of computing and redefine what is possible in technology. As more breakthroughs are made, the prospects for this exciting field will only continue to expand.
A Few Companies Are Developing Quantum Computers
Quantum computers are the next and more advanced form of computing technology that uses quantum bits or qubits instead of classical bits. A few tech companies, including IBM, Google, and Rigetti Computing, have started developing quantum computers to ensure that they lead in this game-changing technology.
The goal is not just to improve performance but also to enable novel functions beyond the capabilities of today’s most advanced supercomputers. The development of a quantum computer requires the right hardware with sufficient coherence time for running the algorithms, appropriate control systems for adjusting laser pulses, and rigorous software optimization techniques. Many technical challenges stand in the way of achieving practical quantum computers, which explains why so few companies are undertaking such endeavors.
IBM’s Quantum Computing Program
IBM has been at the forefront of quantum computing development with its program called IBM Q Network. This program involves building small-scale prototype quantum computers and making them available over the cloud to researchers, engineers, and even businesses for testing and evaluating quantum applications for potential commercial use.
The company introduced its first quantum computer in 2016, and now it boasts 20 quantum computers accessible through the cloud, but only five have reasonably stable quantum processors.
“We don’t yet know all the applications that will be valuable on quantum computers, but we’re committed as an industry community to finding out.” -Dario Gil from IBM research
IBM hopes that creating multiple generations of quantum devices will one day make their quantum computers scalable enough to solve critical problems, like simulating molecules for drug discoveries, optimizing supply chains, detecting frauds, solutions that need massive amounts of computations beyond classical computers’ reach.
Google’s Quantum Computing Program
Google led by CEO Sundar Pichai, has started claiming its progress in the field of quantum computing since 2019. The company’s aim is to create real-world practical uses for their quantum computer research and provide value to that discipline by developing “quantum applications” rather than merely trying out how fast their computers are.
The search giant recently announced it had completed a computation with a quantum processor in three minutes and twenty seconds that would take roughly ten thousand years for the best supercomputers current today to do. Such dramatic increases highlight what may be possible long-term benefits from quantum computing.
“We believe we have attained quantum supremacy, but there still remains a broad technology roadmap ahead within this nascent industry.” –John Martinis
Google plans to offer cloud-based access to some of its prototype hardware as the company tries to refine its quantum algorithms that solve currently unsolvable problems across multiple fields such as chemistry, biology, finance, logistics, and even artificial intelligence. It intends to target these areas first before making quantum cloud services available more widely.
Rigetti Computing’s Quantum Computing Program
Rigetti Computing is an independent organization specialized entirely in quantum computations, which started delivering on its promise from 2017. The company aims to develop completely new ways of computing through creating both software and built-for-purpose quantum chips called Aspen version on a superconducting platform.
The latest chip generation boasts impressive improvements while bringing down error rates and elevating the circuit depth, allowing Rigetti to break into other industries presenting unique quantum solutions. For example, the firm collaborated with NASA Ames Laboratory to simulate optimized material design using quantum machine learning.
“If you ask me if I see anything happening soon like when does it become usable, comercially competitive — nobody knows…I think everybody’s hopeful that we’ll start seeing those applications at scale over the next five to 10 years or so.” -Chad Rigetti (CEO of Rigetti Computing)
The company keeps expanding its Aspen platform and improving chip performance, providing a cheap computing resource through cloud services at a lower cost than traditional supercomputers—a significant feat for companies with smaller research budgets.

Companies like IBM, Google, and Rigetti Computing’s efforts show promise from early applications in quantum computing that may revolutionize various industries. Ongoing developments in hardware viability and software are likely to lead to broader adoption soon.
Quantum Computers Are Still In The Research Stage
Theoretical Research on Quantum Computing
Theoretical research is the first stage towards building a quantum computer. It involves experimenting with different ideas and developing new algorithms that could be implemented into a quantum system.
One of the most promising theoretical advancements in quantum computing is the development of Shor’s algorithm, which is named after its inventor Peter Shor. This algorithm has the ability to find the prime factors of any number faster than traditional computers ever could. A typical desktop computer would take years to factor an integer that is over 200 digits long. However, using Shor’s algorithm on a quantum computer could do the same process in no time, making it very interesting for companies like banks or private data storage.
Another well-known theory in this field is Grover’s search algorithm. This algorithm allows one to search through an unsorted database much quicker and more efficiently than classical methods can. These breakthroughs are key milestones that have brought us closer towards realizing the potential capabilities of quantum computers.
Experimental Research on Quantum Computing
The second stage of developing a quantum computer is in experimental research. This part deals with constructing hardware based on these theories to achieve higher levels of performance. Instead of dealing purely with mathematical formulas on paper, we start to work directly with physical devices in laboratories that will allow us to perform experiments:
- IBM: IBM launched the Q Experience, making it available online to anyone who wants to experiment with their five-qubit universal quantum computer. You can upload your own code and run custom programs on real quantum hardware to see how they work and validate their effectiveness
- D-Wave Systems: D-Wave sells quantum annealing systems at scale for commercial use, although certain aspects about whether their quantum annealing systems are as powerful as traditional quantum computers remain in debate.
Similar to theoretical research, there have been a lot of advancements when it comes to experimental physics related to quantum computing too. Recently Google announced that it had achieved “quantum supremacy” which means performing an operation on the computer faster than any conventional computer could calculate. This was done with a special-purpose superconducting chip called Sycamore; however, other experts question the context and validity of this claim.
“It’s possible to build a machine that can encode more information per qubit than classical bits because through carefully constructed experiments you can assign probabilities to multiple different states simultaneously,” said Scott Aaronson, a professor at Quantum Information Center at the University of Texas at Austin.
The progress evidenced by these advancements is significant and constantly driving us further towards future inventions and discoveries in quantum computing every day. While we still have much work to do before these systems become widespread, the speed with which new technologies and concepts emerge makes me excited for what’s to come next.
Quantum Computers Can Only Be Accessed By Researchers And Scientists
The current availability of quantum computers is quite limited due to the complexity and high cost involved in building them. Quantum computers are not yet commercially available for the general public, indicating that access is restricted only to researchers, scientists, and universities working on their development.
The reason behind this restriction on accessibility is related to the unique nature of quantum computing. Traditional classical computers work based on bits, either a 0 or 1 value. In contrast, quantum computers use qubits that can be zero, one, or both simultaneously. Thus, quantum physics introduces new possibilities for computations beyond the reach of traditional computers.
For instance, it is possible to parallelize several algorithms with superposition states in quantum computing, achieving exponential speedup compared to the classical counterparts. Because of these features, we could solve complex problems such as optimization, cryptography, and machine learning quicker than ever imagined possible.
“The difficulty lies in preparing and manipulating single atoms and photons because they are extremely sensitive to the environment.” -Letitia Pohl Engelhardt, Physicist
The High Cost of Quantum Computing
Since early research into quantum computers began decades ago, building and operating these machines have been expensive and out of reach for most people and businesses. Although some tech giants like IBM, Google, Intel, and Microsoft have made significant investments in quantum technology, the costs associated with quantum hardware require huge capital investment.
According to estimates presented by Cohen et al., in IEEE Spectrum, an employed researcher in a lab running experiments might require about $5 million over five years for adequate quantum resources. However, if the team includes students and post-docs, who may consume more resources through trial-and-error experimentation, the actual price tag could double or triple.
The current quantum computers require significant power consumption and cooling to work at the temperatures close to absolute zero, within fractions of a degree above it. These requirements are expensive too. For instance, IBM’s Quantum Computing website informs that researchers who want full use of their 53-qubit processor must sign up for an enterprise account that costs $10,000 per year.
“Quantum computing is still in its infancy but promises tremendous steps forward in computational ability.” -Tom Stanley
The Need for Specialized Equipment
To access and operate quantum computers, users need specialized equipment beyond regular laptops or computers. The hardware used in building and operating quantum computers requires highly specialized manufacturing capabilities and technologies across many fields.
For example, the qubits themselves are created using sophisticated techniques such as ion implantation and epitaxial growth. They also require superconducting circuits capable of maintaining coherence over long periods and special control electronics to ensure that they function correctly. Furthermore, some machines depend on classical computing resources integrated with quantum computing systems to control and monitor operations. All these lead to requiring special conditions under which they run effectively.
“There’s always been those physical limitations… we’re working against nature here” -Christopher Monroe, Physicist
The Need for Advanced Knowledge and Expertise
Apart from expensive equipment and highly specialized manufacturing techniques, accessing quantum computers needs advanced knowledge and expertise in various scientific disciplines. This involves developing complex algorithms customized to specific quantum processors. Although several programming languages exist today to develop quantum algorithms, most have steep learning curves that only specialists can handle.
Moreover, interfacing between the classical and quantum worlds takes more than software development. As pointed out by Arute et al., physicists and engineers would often rely on analogies between the classical world and the quantum realm to design and test new qubits, control electronics, and firmware. Making the connection between these two distinct worlds is a nontrivial undertaking.
“Well, programming a quantum computer takes some getting used to.” -Seth Lloyd
In conclusion, quantum computers are not yet available on the market due to their high costs, specialized equipment, and complex algorithms that require advanced knowledge and expertise in different scientific fields. These limitations mean that quantum computers can only be accessed by researchers and scientists working in specific labs or universities dedicated to their development.
Quantum Computers Are Being Used In Limited Applications
The creation of quantum computers has been revolutionary in the technological world. This innovation may lead to solving some of the most complex computational problems that classical computers simply cannot handle. Quantum computers use qubits, or quantum bits, which can be in multiple states simultaneously, significantly faster processing speeds than classical computers.
Cryptography and Data Security
One application for quantum computing is cryptography and data security. The current methods used for encryption rely on mathematical problems that are difficult or impossible to solve using classical computers. With the incredible speed and ability to process larger computations, quantum computers have the potential to develop new encryption techniques, breaking classical encryption, and redefining data security entirely.
“Error-correcting codes can detect and correct many errors, but malicious actors can add noise to a message to reduce the effectiveness of these codes and threaten information privacy.” -Rakesh Agrawal, Research Scientist at IBM T.J Watson Research Center
The National Institute of Standards and Technology (NIST) predicts that quantum-resistant cryptographic algorithms need to be implemented by 2025 due to the advancement of quantum computers’ capabilities. Cryptography researchers worldwide are accelerating work to develop new algorithms resistant to such attacks while developing post-quantum cryptographic keys.
Optimization and Simulation
Another limited application where quantum computers have shown practicality is optimization and simulations. Classical computers often struggle with running complex models as they take an extensive amount of time to complete. Quantum computing applications show great potential in calculating optimizations leading to real-world circumstances like airline travel routes or traffic reports.
“Where we anticipate seeing immediate returns is around modeling of natural systems such as biological molecules and chemical reactions.” -Jay Gambetta, Manager of Theory of Quantum Computing group, IBM Quantum Computing
Quantum computing applications can simulate extremely complex molecular systems facilitating the discovery of new compounds or drugs. It allows researchers to predict properties and behaviors of particles that would traditionally take years with current classical computers.
Material Science and Drug Discovery
The ability of quantum computers processing data at a faster rate could provide insight into how materials are formed, affecting energy storage, supply chain management, advancing the development of new pharmaceuticals, and more efficient drug delivery mechanisms.
“The key challenge that material scientists face is that the chemistry determines the electronic structure which ultimately defines material properties.” -Andrew Horsfield, Principal Scientist and Head of Computational Nanoscience research group at BAE Systems Advanced Technology Centre in Bristol
In drug design, utilizing quantum algorithms, experimental techniques, and high-performance simulations can obtain the required quantity of data to determine whether a particular compound will function as predicted chemically, biologically, and numerically.
Quantum Machine Learning
Machine learning typically used by classical computers today is vulnerable to hacks; these systems learn from previous experiences while conducting vital operations such as fraud detection, speech recognition, natural language processing, autonomous driving, and predicting customer behavior. The power of quantum computers accelerates the process by classifying large sets of information simultaneously.
“What excites me most is not the fact that we aren’t sure what problems quantum machine learning might solve but rather that this approach has already demonstrated the potential for exponential speed-up over classical methods” -Iordanis Kerenidis, Director of QML Research at QC Ware Corp at Paris-Saclay University
Although companies like Google and Microsoft claim progress in pushing boundaries on quantum machines’ performance, challenges still need addressing, including developing programming languages for quantum computers, improving performance error rates, and scalability issues. In conclusion, the current availability of quantum computers is limited to research institutions only; they are not yet a commercial product for everyday use.
