Demonstration of quantum volume 64 on a superconducting quantum computing system

Comments

Jay Gambetta: We have increased the quantum volume to 64 on one of our 27-qubit quantum Processors.  This was possible through improving the compiler, calibrating faster two-bit gates, using dynamical decoupling, and an excited state promoted readout. Here is the paper https://arxiv.org/abs/2008.08571 https://t.co/oRXfzpMEFZ

'(Robert Smith): I’m happy to see quantum compilation starting to be taken seriously in IBM’s QV=64 paper. And they didn’t use the word “transpiler”! 🥳 https://arxiv.org/abs/2008.08571 Too bad they didn’t cite what is now considered SOTA in 2Q depth bounds 😏 or quilc 🥺: https://arxiv.org/abs/1904.10541

Stephen Shankland: IBM illustrates this style of progress. It achieved its new quantum volume score of 64 on the same 27-qubit quantum computing hardware it used last year to reach 32. Improvements came from a collection of tweaks, says quantum leader @jaygambetta: https://twitter.com/jaygambetta/status/1296399951497515008
