Hastings-Haah Floquet code[1] 

Description

DA code whose sequence of check-operator measurements is periodic.

Protection

Protects against single-qubit Pauli noise and check operator measurement errors.

Fault Tolerance

Floquet codes on tri-colorable lattices can be made fault-tolerant in the presence of dead qubits [2].

  • Subsystem qubit stabilizer code — This code can be viewed as a subsystem stabilizer code, albeit one with less logical qubits.
  • Monitored random-circuit code — Both Floquet and monitored random circuit codes can have an instantaneous stabilizer group which evolves through unitary evolution and measurements. However, Floquet codewords are generated via a specific sequence of measurements, while random-circuit codes maintain a stabilizer group after any measurement. Floquet codes have the additional capability of detecting errors induced during the measurement process; see Appx. A of Ref. [1].
  • Majorana stabilizer code — Floquet codes are viable candidates for storage in Majorana-qubit devices [3].
