DOI: 10.1007/s11467-019-0949-5

Abstract: We propose a method for transferring quantum entangled states of two photonic cat-state qubits ( cqubits ) from two microwave cavities to the other two microwave cavities. This proposal is realized by using four microwave… read more here.

DOI: 10.1103/physreva.98.063814

Abstract: We analyze a method for the creation, storage and retrieval of optomechanical Schrodinger cat states, in which there is a quantum superposition of two distinct macroscopic states of a mechanical oscillator. In the proposal, an… read more here.

Abstract: We propose a method to subtract a photon from a double sideband mode of continuous-wave light. The central idea is to use phase modulation as a frequency sideband beam splitter in the heralding photon subtraction… read more here.

DOI: 10.1103/physrevlett.130.213604

Abstract: The ability to prepare a macroscopic mechanical resonator into a quantum superposition state is an outstanding goal of cavity optomechanics. Here we propose a technique to generate Schr\"odinger cat states of motion using the intrinsic… read more here.
