Random-circuit code[1]
Description
Code whose encoding is naturally constructed by randomly sampling from a large set of (not necessarily unitary) quantum circuits.
Protection
A useful proxy and upper bound to the code distance \(d\) is the contiguous code distance: the contiguous length (with periodic boundary conditions) of the shortest logical operator [2,3].
Notes
Parents
Children
- Monitored random-circuit code — Monitored random circuits are random circuits where projective measurements are interspersed throughout the circuit and measurement results are recorded.
- Haar-random qubit code
- Low-depth random Clifford-circuit qubit code
- Local Haar-random circuit qubit code
Cousin
- Crystalline-circuit qubit code — Crystalline-circuit codes can be thought of as random-circuit codes with symmetries.
