“…So far, many schemes [7][8][9][10][11][12][13][14][15] have been proposed to prepare entangled states and to realize remote quantum logic gates based on atoms separately trapped in cavities coupled by fibers. All of them can be implemented with high fidelity and are robust against the decoherence.…”

With the quantum Zeno dynamics, we propose a scheme for implementing the remote three-qubit controlled-Z gate with three -type atoms trapped in three spatially separated cavities coupled by optical fibers. It can be implemented by one step and doesn't require strong cavity-fiber coupling. Moreover, the influences of various decoherence processes, such as spontaneous emission and photon leakage of cavities and fibers, on the fidelity are also investigated by numerical calculation. The result shows that our scheme is robust against the decoherence and promising for the realization with current experimental technology.

“…There have been many proposals for creating atomic entanglement [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17], meanwhile some notable experimental demonstrations have also been performed. But in practical realization, every quantum system is open and unavoidable interaction with its environment which results in dissipation and destruction of entanglement.…”

We report possibility of generating entanglement and steady entanglement between two identical atoms in free space with a very natural way when their spatial separation is on the order of wavelength or less. We show a dynamical creation of entanglement and steady entanglement due to the radiative coupling with different separable initial atomic states and study the entanglement properties about this atomic subsystem. Not only the creation of steady state entanglement is decided by the initial atomic states, but also the magnitude of the entanglement and the steady state entanglement are found to be strongly dependent on the initial states. We derive a master equation for the atomic subspace and solve it analytically to show how the spontaneous emission from the two atoms system induces entanglement and steady entanglement, the crossing coupling terms in master equation can enhance the entanglement value.

“…The coupled atomcavity-fiber systems are regarded as one of the most promising candidates for implementing distributed computation. Some schemes have been proposed for entanglement engineering for two or more atoms trapped in distant cavities connected by a fiber or fibers [15][16][17][18][19][20] and in coupled cavities [21,22]. In this paper, we propose a scheme for generation of NOON states for two atomic samples trapped in two distant optical cavities.…”

Generation of NOON Sates for Two Atomic Samples Trapped in Two Distant Cavities

A scheme is proposed for generating NOON states for two atomic samples trapped in two distant cavities connected by a third cavity and optical fibers. In the scheme, all the atoms are always populated in the two degenerate ground states, so the atoms' spontaneous emission can be omitted approximately. During the operation neither the cavity modes nor fiber modes are excited, which is important in view of decoherence. The scheme does not include projective measurement and the NOON state is generated deterministically.
