Linear-optical approach to encoding qubits into harmonic-oscillator modes via quantum walks
Jun-Yi Wu, Shin-Tza Wu
We propose a linear-optical scheme that allows encoding grid-state quantum bits (qubits) into a bosonic mode using cat state and post-selection as sources of non-Gaussianity in the…
The Wigner flow on the sphere
P. Yang, I. F. Valtierra, A. B. Klimov +4
We derive a continuity equation for the evolution of the SU(2) Wigner function under nonlinear Kerr evolution. We give explicit expressions for the resulting quantum Wigner current…
Encoding qubits into harmonic-oscillator modes via quantum walks in phase space
Chai-Yu Lin, Wang-Chang Su, Shin-Tza Wu
We provide a theoretical framework for encoding arbitrary logical states of a quantum bit (qubit) into a continuous-variable quantum mode through quantum walks. Starting with a squ…
Entanglement enhancement through multi-rail noise reduction for continuous-variable measurement-based quantum information processing
Yung-Chao Su, Shin-Tza Wu
We study theoretically the teleportation of controlled-phase (CZ) gate through measurement-based quantum information processing for continuous-variable systems. We examine the degr…
Quenched decoherence in qubit dynamics due to strong amplitude-damping noise
Shin-Tza Wu
We study non-perturbatively the time evolution of a qubit subject to amplitude-damping noise. We show that at strong coupling the qubit decoherence can be quenched owing to large e…
Exact dynamics for optical coherent-state qubits subject to environment noise
Ming-Jay Yang, Shin-Tza Wu
We study the exact dynamics of optical qubits encoded via coherent states with opposite phases which are interacting with an environment modeled as a collection of simple harmonic…
