Quantum error correction

Inside

A record carries more than one topic, so these add up to more than the folder holds.

• Error correction

  2 records

  Codes, syndromes, decoders, and the magic states fault tolerance consumes.

• Operator

  2 records

  A Hamiltonian, observable, or measurement operator — something to measure, not something to run.

• Stabilizer

  2 records

  Clifford circuits, graph and cluster states, and syndrome measurement — the classically simulable corner.

Records here

• Shor nine-qubit error-correction code

  Quantum error correction

• Surface-code memory and biased-noise decoding
