Quantum information science is a rapidly emerging field with promises for development in a broad range of areas, including quantum computing, quantum simulation, quantum communication, and quantum metrology and sensing. This year’s Nobel Prize in Physics was awarded to Alain Aspect, John F. Clauser, and Anton Zeilinger to honor and celebrate their contributions to quantum technology. Together, these advancements will allow scientists to create quantum computers and secure cryptographic systems at breakneck speeds. Companies and academic organizations are spending millions of dollars on quantum technology research to make these ideas a reality. So let’s explore the top 10 companies that have invested and are working in the field of quantum computing.
When IBM unveiled the IBM Q System One, the world’s first commercial quantum computer, it blazed a trail in the emerging field of quantum computing. Its cloud-based quantum computing services, both free and paid, have made it the market leader in this area of technology. They unveiled the 127-qubit Eagle processor in 2021 and plan to manufacture the 433-qubit Osprey processor and the 1,000-plus-qubit Condor processor in the near future.
Quantum Artificial Intelligence Lab is a new initiative from Google, NASA, and USRA to advance quantum computing systems with the potential to improve the efficiency of AI algorithms and provide solutions to pressing societal challenges. Over the years, they’ve built and released a number of frameworks, libraries, and quantum hardware. New quantum algorithms are constructed and optimized with the help of open-source libraries like OpenFermion and Tensorflow Quantum. They’ve also created the Cirq python package, which can be used to create, modify, and optimize quantum circuits before testing them on quantum computers and simulators.
Azure is the first cloud platform to offer open, end-to-end quantum computing services, and Microsoft is the pioneer in this space. An open-source, high-level quantum programming language called Q# has also been released as part of a quantum development kit for the benefit of programmers. Microsoft has recently invented a new type of qubit called a topological qubit, which the company claims will be faster, smaller, and more dependable than previous types of qubits.
Another major IT company with a stake in quantum computing development is Amazon. Amazon has announced the availability of Amazon Braket, a cloud-based quantum computing tool designed to speed up a variety of scientific and software development processes. Users can gain access to several varieties of quantum computers at a price that is both reasonable and well-managed.
D-Wave Systems is a pioneer in the field of quantum computing. Instead of being run as a universal gate-model quantum computer, their processors use a revolutionary mechanism termed quantum annealing. Leap, D-Wave’s cloud-based quantum computing service, is aimed at the general public, whereas Leap 2, aimed at developers and industry, is used to create applications with significant real-world impact.
Intel, a large semiconductor manufacturer, has made numerous contributions to the field of quantum computing. They took their experience making high-volume transistors and applied it to the development of ‘hot’ silicon spin-qubits, which are both more compact and more resistant to high temperatures. Horse Ridge, Intel’s first cryogenic control chip, paves the way for the company to create full-stack quantum computing systems. With this control device, numerous quantum bits can be managed, marking a major advancement toward quantum practicality. Intel has also introduced Horse Ridge II, which has improved capabilities to read and write qubit states and to modify the potential of many gates required to entangle multiple qubits.
Rigetti Computing provides quantum computing services on the cloud and builds quantum integrated circuits. Forest, a cloud computing platform, allows developers to create and test their quantum algorithms in their designed language, QuIL (Quantum Instruction Language). The software development kit for management of the programming language includes language extensions, Quil-T, Python library, pyQuil, compiler, Quillc, and Quantum Virtual Machine. In addition, they have a fabrication lab called Fab-1 to create state-of-the-art integrated circuits for quantum hardware.
Toshiba has been working on quantum cryptography for secure network communication. With all the progress being made in quantum computing, it won’t be long until such quantum computers can break our present encryption techniques in a matter of seconds. Accordingly, major advances in safe data transmission are urgently required. Toshiba offers two versions of Quantum Key Distribution: the multiplexed QKD systems and large distance QKD systems.
Along with Cambridge Quantum, Honeywell has developed the world’s largest integrated quantum computing corporation under the brand name Quantinuum. They are experts in the field of developing ion trap quantum computers. It is referred to as “Nature’s Qubit” since atomic structure serves as the basis for its definition in the natural world. These systems are easily and quickly controlled and uniformly manufactured as they are all identical and defect-free. The next-generation System Model H1 quantum computer has also been released. This quantum computer also makes use of trap-ion technology.
QC Ware is a nascent Quantum Computing as a Service (QCaaS) provider that offers businesses and organizations access to quantum computing technologies for use in a variety of different applications and processes. To help businesses and government agencies reap the benefits of quantum computing, they have released the cloud platform Forge. With their help, even specialists who have never worked with quantum computers can learn the ropes and create their own cutting-edge programs.
