Top 10 Quantum Computers of 2023

Top 10 quantum computers based on available data. However, it's worth noting that this list may change rapidly, as quantum computing technology is advancing rapidly.

1.Google Sycamore:

The Google Sycamore quantum computer is a 54-qubit machine that made headlines in 2019 for achieving quantum supremacy - the point at which a quantum computer can perform a calculation that no classical computer can solve in a reasonable amount of time.

2.IBM Quantum Experience:

IBM Quantum Experience is a cloud-based quantum computing platform that provides access to IBM's fleet of quantum computers. The platform includes machines ranging from 5 to 65 qubits, including the IBM Q System One, the first commercial quantum computer.

3. IonQ:

IonQ is a quantum computing company that has built a trapped-ion quantum computer with 32 qubits. Their system is based on a technology called ion trapping, which uses electric and magnetic fields to trap individual atoms and use them as qubits.

4. Rigetti:

Rigetti is a quantum computing company that has built a quantum computer with 31 qubits. Their system is based on a technology called superconducting qubits, which use superconducting circuits to control and manipulate quantum states.

5. Honeywell:

Honeywell is a technology company that has built a trapped-ion quantum computer with 10 qubits. They have also announced plans to release a 20-qubit system in the near future.

6. Xanadu:

Xanadu is a quantum computing company that has built a photonic quantum computer with 8 qubits. Their system is based on a technology called continuous-variable quantum computing, which uses the properties of light to encode quantum information.

7. D-Wave:

D-Wave is a quantum computing company that has built a quantum annealer with over 5000 qubits. Their system is based on a technology called quantum annealing, which uses the principles of quantum mechanics to solve optimization problems.

8. QuTech:

QuTech is a research institute in the Netherlands that is working on developing quantum computing technology. They have built a superconducting quantum computer with 5 qubits, as well as a hybrid system that combines superconducting and spin qubits.

9. Zapata Computing:

Zapata Computing is a quantum computing company that provides quantum software and algorithms. They work with a variety of hardware platforms, including superconducting qubits, trapped ions, and photonic qubits.

10. Alibaba:

Alibaba is a Chinese e-commerce company that has built a quantum computer with 11 qubits. Their system is based on a technology called superconducting qubits, and they have announced plans to release a 50-qubit system in the near future.

Overall, these are just a few of the quantum computers that are currently in development or have been released in the market. The field of quantum computing is rapidly evolving, and we can expect to see many more quantum computers emerging in the near future.
