Also known as Verstraete-Cirac code, Auxiliary fermion code.
Description
A 2D fermion-into-qubit encoding that builds upon the JW transformation encoding by eliminating the weight-\(O(n)\) \(X\)-type string at the expense introducing additional qubits. See [3; Sec. IV.B] for details.
Protection
Some single-qubit errors are detectable, with the rest inducing low-weight fermionic dephasing noise [4].
Parents
- Quantum error-transmuting code (QETC) — The BVC code transmutes all single-qubit errors [5].
- Fermion-into-qubit code
Cousin
- Rotated surface code — An appropriately chosen stabilizer generator set for the BVC code contains the stabilizers of the rotated surface code [6].
