Correlation-Assisted Odd-Parity Encoded Gates in Coupled Fluxonium Qubits under Non-Markovian TLS Noise
Chenghong Ji, Chaoying Zhao
Correlated longitudinal noise can be partially converted into common-mode fluctuations in an oddparity two-qubit subspace. We analyze an encoded logical qubit formed by the states…

Spin Squeezing of One-Axis Twisting Model in The Presence of Phase Dephasing
C. G. Ji, Y. C. Liu, G. R. Jin
We present a detailed analysis of spin squeezing of the one-axis twisting model with a many-body phase dephasing, which is induced by external field fluctuation in a two-mode Bose-…
