At Google Quantum AI, we have a long history of making tools we build for our own research available to the public free of cost. Today we are adding the Quantum Virtual Machine to the list. The Quantum Virtual Machine (QVM) emulates the experience and results of programming one of the quantum computers in our lab, from circuit validation to processor infidelity. We feed measurements from our Sycamore processors, such as qubit decay, dephasing, gate and readout errors into the QVM and combine these with the qubit connectivity of the device to simulate quantum processor-like output, using our physics research team’s models. You can see comparisons between results obtained from experiments on a Sycamore chip and the QVM here.
