Generation of superposition coherent states of microwave fields via dissipation of a superconducting qubit with broken inversion symmetry

2019 · Physical Review A

We present an efficient approach for dissipative generation of quantum superposition states in the microwave resonator, which is coupled to a superconducting qubit. We investigate the situation where the inversion symmetry of potential energy of …

Optimal phase sensitivity by quantum squeezing based on a Mach–Zehnder interferometer

2019 · New Journal of Physics

Abstract A novel scheme for the enhancement of phase sensitivity based on a Mach–Zehnder interferometer (MZI) and intensity detection is proposed. With the input of bright entangled twin beams from four wave mixing (FWM), the …

Effects of reservoir squeezing on trace-distance correlations and emergence of the pointer basis

2023 · Physical Review A

We investigate theoretically the dynamics of 1-norm geometric quantum correlations and their classical counterparts in a two-qubit system. Both qubits are initially prepared in Bell-diagonal states and locally coupled to separated thermal squeezed baths or …
