Fermionic code 

Description

Finite-dimensional quantum error-correcting code encoding a logical Hilbert space into a physical Fock space of fermionic modes. Codes are typically described using Majorana operators, which are linear combinations of fermionic creation and annihilation operators [1].

Gates

Clifford operations on fermionic codes can often be formulated using linear optics [2–4].

Notes

See Ref. [5] for an introduction into Majorana-based qubits.

Parent

  • Qubit code — The Majorana operator algebra is isomorphic to the qubit Pauli-operator algebra via the Jordan-Wigner transformation [6]. However, Majorana codes and the noise they are designed for are based on a different notion of locality.

Child

Cousin

  • Bosonic code — Bosonic (fermionic) codes are associated with bosonic (fermionic) degrees of freedom.
