Abstract EN
For eliminating the unexpected decoherence effect in cavity quantum electrodynamics (cavity QED), the transfer function of Rabi oscillation is derived theoretically using optical Bloch equations.
In particular, the decoherence in cavity QED from the atomic spontaneous emission is especially considered.
A feedback control strategy is proposed to preserve the coherence through Rabi oscillation stabilization.
In the scheme, a classical quantum feedback channel for the quantum information acquisition is constructed via the quantum tomography technology, and a compensation system based on the root locus theory is put forward to suppress the atomic spontaneous emission and the associated decoherence.
The simulation results have proved its effectiveness and superiority for the coherence preservation.
