Quantum state transfer using stimulated Raman adiabatic passage under a dissipative environment

摘要

We propose a potentially practical scheme to realize arbitrary quantum state transfer between two travelingnatoms that go through a high-finesse cavity by using stimulated Raman adiabatic passage in an atom-cavity-lasernsystem under a dissipative environment. By numerically simulating the dynamics of the system, we demonstratenquantitatively that the fidelities of the quantum state transferred between two atoms can be maximized bynelaborately adjusting the peak amplitudes of the laser’s Rabi frequency and the detuning of the Raman transition.nAdditionally, the noise effect from the atomic and cavity dissipation can reduce the fidelity. The experimentalnfeasibility is justified using currently available technology.
