Propagating Gottesman-Kitaev-Preskill states encoded in an optical oscillator
Shunya Konno, Warit Asavanant, Fumiya Hanamura +14
A quantum computer with low-error, high-speed quantum operations and capability for interconnections is required for useful quantum computations. A logical qubit called Gottesman-K…
Nonlinear feedforward enabling quantum computation
Atsushi Sakaguchi, Shunya Konno, Fumiya Hanamura +9
Measurement-based quantum computation with optical time-domain multiplexing is a promising method to realize a quantum computer from the viewpoint of scalability. Fault tolerance a…
Non-Clifford gate on optical qubits by nonlinear feedforward
Shunya Konno, Warit Asavanant, Kosuke Fukui +6
In a continuous-variable optical system, the Gottesman-Kitaev-Preskill (GKP) qubit is a promising candidate for fault-tolerant quantum computation. To implement non-Clifford operat…
Estimation of Gaussian random displacement using non-Gaussian states
Fumiya Hanamura, Warit Asavanant, Kosuke Fukui +2
In continuous-variable quantum information processing, quantum error correction of Gaussian errors requires simultaneous estimation of both quadrature components of displacements o…
Nonlinear squeezing for measurement-based non-Gaussian operations in time domain
Shunya Konno, Atsushi Sakaguchi, Warit Asavanant +6
Quantum non-Gaussian gate is a missing piece to the realization of continuous-variable universal quantum operations in the optical system. In a measurement-based implementation of…
