Quantum computing, a field that has seen significant advancements in recent years, is poised to revolutionize the way we process data. At the heart of this technology are quantum bits, or qubits, which can assume a value of one and zero simultaneously due to a quantum phenomenon known as superposition. This unique characteristic allows quantum computers to process information in ways that classical computers cannot, opening up new possibilities for applications, particularly in simulating the natural world.
What is Quantum computing?
Quantum computing is a type of computing that leverages the principles of quantum mechanics to perform calculations. Unlike classical computing, which uses bits to represent a 0 or a 1, quantum computing uses quantum bits or qubits. A qubit can exist in a superposition of states, allowing it to represent both 0 and 1 simultaneously.
The key principles that make this new technology a unique are superposition, entanglement, and quantum gates. Superposition enables parallelism at the qubit level, meaning a quantum computer can explore multiple solutions at once. Entanglement allows qubits that are entangled to be correlated with each other; changing the state of one instantly affects the state of the other, no matter the distance separating them. Quantum gates manipulate an input of qubits into a different output of qubits by changing the probabilities of the qubits’ states.
Because of these properties, quantum computers have the potential to solve certain problems much faster than classical computers. For example, they could excel at optimization problems, factorization, and simulation of quantum systems. However, building a practical, scalable quantum computer is a significant engineering challenge due to issues like qubit stability (decoherence) and error rates.
Investment
IBM, Google, Microsoft, and Amazon are among the leading companies investing heavily in quantum computing. IBM has been at the forefront, with its IBM Q Network, a community of Fortune 500 companies, academic institutions, and research labs working on quantum computing. Google, on the other hand, claimed “quantum supremacy” in 2019 when its quantum computer solved a problem in 200 seconds that would take a supercomputer 10,000 years. Microsoft is developing a topological qubit that could make quantum computers more stable and easier to control. Amazon, meanwhile, offers quantum computing as a service through its cloud platform, AWS.
In the past, quantum computer ardour was largely confined to experimental labs. However, the landscape has changed dramatically. Tech giants like IBM and Google have been at the forefront of developing experimental quantum computers. IBM, for instance, announced a 433 qubit Osprey processor in November 2022. D-Wave Systems, another pioneer in the field, boasts a quantum computer with over 5000 qubits.
Availability via Cloud access
But this new powerful technology is not just for tech giants. Cloud access to quantum computer processing is now available from major providers like Microsoft Azure and Amazon Web Services, who have partnered with quantum hardware pioneers. This has democratized access to the latest technology, allowing a wider range of researchers and developers to experiment with this cutting-edge technology.
Despite these advancements, quantum computers are not intended to replace classical computers. Instead, they offer a new way to run applications, particularly those that simulate the natural world. This is because quantum computers can process vast amounts of data simultaneously, making them ideal for tasks that require complex computations.

However, quantum computing is not without its challenges. Qubits are highly susceptible to noise from the environment or component imperfections, which can lead to errors in the results. To overcome this, quantum pioneers are working on refining existing qubit technologies, improving quantum error correction, and developing new qubit technologies. IBM and Google, for instance, have reported progress in quantum error correction and the manipulation of noise.
Superconducting qubits
Various methods are being used to create quantum states of matter for computation. These include superconducting qubits, trapped iron qubits, photonic qubits, and silicon spin qubits. Intel has even released a new 12 qubit quantum research silicon chip called Tunnel Falls, which is available to universities and federal labs for research. Other technologies being developed include neutral atom qubits and topological qubits based on Majorana zero modes.
Microsoft, for its part, is focusing on developing topological qubits and has released experimental data and simulations of their topological quantum devices. Microsoft’s Azure Quantum is also supporting the wider quantum computing ecosystem by providing online resources for learning about quantum computers and programming.
Applications
Interest in the potential applications of larger scale, fault-tolerant quantum computers is growing. Funding is being provided by organizations like DARPA and the Australian government to further explore these possibilities. It is predicted that a large-scale, fault-tolerant quantum computer will be built in the next 10 years. Such a computer could be used for tasks like molecular modeling to improve our understanding of chemistry and material science.
In a rapidly evolving field, with significant advancements being made in both hardware and software. While challenges remain, the potential of this technology to revolutionize computing is undeniable. As we move forward, we can expect to see this powerful technology become an increasingly important part of our digital landscape.
