Abstract: In the present work we study the influence of both the fluctuation effects of the atom velocity and the atomic decay on the fidelity corresponding to a protocol for the quantum state transfer between two… read more here.

Abstract: Abstract In this paper, we outline a scheme for entanglement swapping based on the concept of cavity QED. The atom–field entangled state in our study is produced in the nonlinear regime. In this scheme, the… read more here.

Abstract: We propose a quantum metrology scheme in a cavity QED setup to achieve the Heisenberg limit. In our scheme, a series of identical two-level atoms randomly pass through and interact with a dissipative single-mode cavity.… read more here.

DOI: 10.1515/nanoph-2021-0718
Abstract: Abstract A quantum dipole interacting with an optical cavity is one of the key models in cavity quantum electrodynamics (cavity-QED). To treat this system theoretically, the typical approach is to truncate the dipole to two… read more here.
