Quantum error correction of spin quantum memories in diamond under a zero magnetic field

HIGHLIGHTS

  • who: Takaya Nakazato from the Graduate School National University, Tokiwadai, Hodogaya, Yokohama, Japan have published the paper: Quantum error correction of spin quantum memories in diamond under a zero magnetic field, in the Journal: (JOURNAL) of 25/03/2022
  • what: Although complete QEC is achieved by a nine-qubit code the authors demonstrate a three-qubit code that can correct either a bitflip error (Fig 3a) or a phase-flip error (Fig 3b) which are otherwise identical except for the Hadamard gates inserted immediately after encoding and before decoding. The authors compare the results with . . .
