This paper realizes a nondestructive and complete Bell-state analysis for atomic qubit systems by a designed nondestructive and complete Bell-state analyser. In the scheme, Bell states are completely discriminated by two bits of classical informations which comes from the locality single atom detection on two auxiliary atoms, during which the Bell states are not affected. The needed devices are well within the bounds of current technology, and then the scheme is experimentally feasible. 相似文献

We propose a scheme to generate two-atom maximally entangled state in cavity quantum electrodynamies (QED). The scheme can 5e extended to generation of entangled multi-atom Dicke states if we control the interaction time of atoms with cavity modes. We use adiabatically state evolution under large atom-cavity detuning, so the scheme is insensitive to atomic spontaneous decay. The influence of cavity decay on fidelity and success probability is discussed. 相似文献

The principle and experimental results of the open microwave resonant cavity measurement system were introduced. The models were steel ball models and the ball models coated with copper. The diameter of the models was 10mm . The models were launched in ballistic range. The model velocity was 5.44 km .s-1. The wake electron density of the models was obtained. The experimental results presents that the response time of the open microwave resonant cavity measurement system was quicker than 1ms. The results showed the wake electron density ranged from 109cm -3 to 1011cm -3 could be achieved. 相似文献

The increasing level of experimental control over atomic and optical systems gained in recent years has paved the way for the exploration of new physical regimes in quantum optics and atomic physics, characterised by the appearance of quantum many‐body phenomena, originally encountered only in condensed‐matter physics, and the possibility of experimentally accessing them in a more controlled manner. In this review article we survey recent theoretical studies concerning the use of cavity quantum electrodynamics to create quantum many‐body systems. Based on recent experimental progress in the fabrication of arrays of interacting micro‐cavities and on their coupling to atomic‐like structures in several different physical architectures, we review proposals on the realisation of paradigmatic many‐body models in such systems, such as the Bose‐Hubbard and the anisotropic Heisenberg models. Such arrays of coupled cavities offer interesting properties as simulators of quantum many‐body physics, including the full addressability of individual sites and the accessibility of inhomogeneous models. 相似文献

This paper proposes an experimentally feasible scheme for
teleportation of an unknown two-atom entangled state, where a
cluster state is used as the quantum channel. This scheme does not
need any joint measurement. In addition, the successful probability
and fidelity of teleportation can both reach 1.0. The current scheme
can be realized within the current experimental technology. 相似文献
