Faster Quantum Computing Now Possible Despite Increased Error Rates

Faster Quantum Computing Now Possible Despite Increased Error Rates

Local robust shadows on a trapped ion computer, a case study Achieving 96% fidelity in a shadow protocol represents a new balance between speed and accuracy in quantum computation. This work implements a complete local robust shadows pipeline with Pauli-X-twirling, overcoming increased error rates caused by faster measurement times. The technique enables quicker experiments without compromising the reliability of results from trapped-ion quantum…
