Classification: CPC H  G | IPC G  H

Claim 11:
12. A method of performing quantum error correction, the method comprising:
initializing a first Gottesman-Kitaev-Preskill (GKP) state in a first ancilla quantum mechanical oscillator;
entangling information stored in a first data quantum mechanical oscillator with information stored in the first ancilla quantum mechanical oscillator;
disentangling the information stored in the first data quantum mechanical oscillator and the information stored in the first ancilla quantum mechanical oscillator;
measuring position and momentum quadrature operators of the first ancilla quantum mechanical oscillator; and
using the measured position and momentum quadrature operators to correct for an error in the information stored in the first data quantum mechanical oscillator.
