1. A method of producing a magic state for a quantum computer, the method comprising steps of:
providing a Gaussian quantum computer including a circuit;
generating a Gaussian input state of the circuit;
applying a bosonic error correction code to the Gaussian input state, wherein the bosonic error correction code is a Gottesman-Kitaev-Preskill (GKP) error correction code consisting of Gaussian operations and a GKP Pauli eigenstate, the GKP error correction code requiring no non-Gaussian resources beyond the GKP Pauli eigenstate and requiring no additional external qubits, and
producing the magic state.
