HIGHLIGHTS
- who: Zhongchu Ni from the (UNIVERSITY) have published the research: Beating the break-even point with a discrete-variable-encoded logical qubit, in the Journal: (JOURNAL) of 16/Nov/2022
- what: The authors demonstrate a QEC procedure in a circuit quantum electrodynamics architecture18, where the logical qubit is binomially encoded in photon-number states of a microwave cavity8, dispersively coupled to an auxiliary superconducting qubit. The authors demonstrate this procedure with the lowest-order binomial code and extend the stored quantum information lifetime 16% longer than the best physical qubit, encoded in the two lowest . . .
