Distance-four quantum codes with combined postselection and error correction
Prithviraj Prabhu, Ben W. Reichardt
When storing encoded qubits, if single faults can be corrected and double faults postselected against, logical errors only occur due to at least three faults. At current noise rate…
Fault-tolerant syndrome extraction and cat state preparation with fewer qubits
Prithviraj Prabhu, Ben W. Reichardt
We reduce the extra qubits needed for two fault-tolerant quantum computing protocols: error correction, specifically syndrome bit measurement, and cat state preparation. For distan…
Short Shor-style syndrome sequences
Nicolas Delfosse, Ben W. Reichardt
We optimize fault-tolerant quantum error correction to reduce the number of syndrome bit measurements. Speeding up error correction will also speed up an encoded quantum computatio…
Quantum dimension test using the uncertainty principle
Rui Chao, Ben W. Reichardt
We propose a test for certifying the dimension of a quantum system: store in it a random -bit string, in either the computational or the Hadamard basis, and later check that the…
Beyond single-shot fault-tolerant quantum error correction
Nicolas Delfosse, Ben W. Reichardt, Krysta M. Svore
Extensive quantum error correction is necessary in order to perform a useful computation on a noisy quantum computer. Moreover, quantum error correction must be implemented based o…
Flag fault-tolerant error correction for any stabilizer code
Rui Chao, Ben W. Reichardt
Conventional fault-tolerant quantum error-correction schemes require a number of extra qubits that grows linearly with the code's maximum stabilizer generator weight. For some comm…
