IBM has upgraded one of its newest 27-qubit client-deployed systems to achieve a Quantum Volume 64. Congratulations to IBM for advancing quantum computer technology that matches the best quantum volume metric for a quantum computer. Honeywell also claims a Quantum Volume 64 quantum computer. The best a regular non-quantum computer working on the type of problems has achieved the equivalent of a Quantum volume of 4096. This is explained below.

IBM used new techniques and improvements that used knowledge of the hardware to optimally run the Quantum Volume circuits. These hardware-aware methods are extensible and will improve any quantum circuit run on any IBM Quantum system, resulting in improvements to the experiments and applications which users can explore. These techniques will be available in upcoming releases and improvements to the IBM Cloud software services and the cross-platform open-source software development kit (SDK) Qiskit.
