Classification: CPC H  G | IPC G  H

Claim 0:
1. A quantum information device, comprising:
a plurality of quantum mechanical oscillators, comprising:
a first data quantum mechanical oscillator configured to store information representing a first data state; and
a first ancilla quantum mechanical oscillator coupled to the first data quantum mechanical oscillator, the first ancilla quantum mechanical oscillator configured to store information representing a first ancilla state, wherein the first ancilla state is initialized as a first Gottesman-Kitaev-Preskill (GKP) state;

at least one electromagnetic radiation source coupled to the plurality of quantum mechanical oscillators and configured to entangle and/or disentangle the information stored in the first data quantum mechanical oscillator and the information stored in the first ancilla quantum mechanical oscillator by applying one or more drive waveforms to one or more quantum mechanical oscillators of the plurality of quantum mechanical oscillators; and
at least one measurement device coupled to the first ancilla quantum mechanical oscillator, the at least one measurement device configured to measure a position quadrature operator and/or a momentum quadrature operator of the first ancilla quantum mechanical oscillator.
