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].Cousin
- Crystalline-circuit qubit code— Crystalline-circuit codes can be thought of as random-circuit codes with symmetries.

Monitored random circuits are random circuits where projective measurements are interspersed throughout the circuit and measurement results are recorded.
