Verifying Multipartite Entangled GHZ States via Multiple Quantum Coherences
Ken X. Wei, Isaac Lauer, Srikanth Srinivasan +6
The ability to generate and verify multipartite entanglement is an important benchmark for near-term quantum devices devices. We develop a scalable entanglement metric based on mul…

Validating quantum computers using randomized model circuits
Andrew W. Cross, Lev S. Bishop, Sarah Sheldon +2
We introduce a single-number metric, quantum volume, that can be measured using a concrete protocol on near-term quantum computers of modest size (), and measure it o…

Procedure for systematically tuning up crosstalk in the cross resonance gate
Sarah Sheldon, Easwar Magesan, Jerry M. Chow +1
We present improvements in both theoretical understanding and experimental implementation of the cross resonance (CR) gate that have led to shorter two-qubit gate times and interle…
