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…

Recognition of Schrodinger cat state based on CNN
Tao Zhang, Chaoying Zhao
We applied convolutional neural networks to the classification of cat states and coherent states. Initially, we generated datasets of Schrodinger cat states and coherent states fro…

Realization of two-qubit gates and multi-body entanglement states in an asymmetric superconducting circuits
Tao Zhang, Chaoying Zhao
In recent years, the tunable coupling scheme has become the mainstream scheme for designing superconducting quan tum circuits. By working in the dispersive regime, the ZZ coupling…
