Generation of multi-atom entangled states in coupled cavities via transitionless quantum driving

Generation of multi-atom entangled states in coupled cavities via transitionless quantum driving In this paper, we propose an efficient scheme to generate three-atom W states in spatially separated cavities connected by optical fibers. In the scheme, we combine the “transitionless quantum driving” with “quantum Zeno dynamics” to construct a shortcut to fast generate W states. Comparing with the traditional adiabatic passage, the significant advantage is that the interaction time required for the creation of the W state is much shorter, which is very important in view of decoherence.

Abstract

In this paper, we propose an efficient scheme to generate three-atom W states in spatially separated cavities connected by optical fibers. In the scheme, we combine the “transitionless quantum driving” with “quantum Zeno dynamics” to construct a shortcut to fast generate W states. Comparing with the traditional adiabatic passage, the significant advantage is that the interaction time required for the creation of the W state is much shorter, which is very important in view of decoherence. Furthermore, the harmful effects of various decoherence such as atomic spontaneous emission, cavity losses and the fiber photon leakages are considered. Numerical simulations illustrate that the shortcut scheme is much faster than the schemes using adiabatic passage and robust against the decoherence. Moreover, this scheme can also be generalized to generation of N-atom W states.
