The UK’s second commercial quantum computer has come online

California-based quantum circuitry company Rigetti has brought a commercially available quantum computer to the UK. Only the second in the country, it was installed in collaboration with Oxford Instruments NanoScience — a cryogenics company that provides the cooling needed for superconducting qubits.  The system, supported by grants from the UK government, is Rigetti’s first UK-based quantum computer and will be accessible via the company’s cloud computing services.
