Frequently Asked Questions
Which quantum processor type is best?
It depends on the use case. Superconducting qubits are fast, ion traps are stable, and photonic qubits promise speed and ambient operation. Learn more at Quantum Computing UK.
Are quantum processors commercially available?
Yes. IBM, Rigetti (Rigetti Computing), IonQ, and others offer access via cloud-based quantum computing services.
What is quantum decoherence?
It's the loss of quantum information due to interaction with the environment. Minimizing it is key to reliable quantum computing.
