Abstract:
We propose a scheme to fast controlled preparation of two-atom maximally entangled state and N-atom W state in the directly coupled cavities systems via shortcuts to adiabatic passage (STAP). Numerical simulation demonstrates that the scheme is faster than adiabatic passage and robust against the decoherence caused by atomic spontaneous emission and photon leakage. The result provides a theoretical basis for the manipulation of quantum states in the directly coupled cavities systems via STAP and contributes to the understanding of more complex systems.
