摘要:

我们考虑通过辅助系统与初始不相关的量子比特的顺序耦合来确定性地产生纠缠多量子比特态。我们描述了所有可实现的状态的矩阵乘积状态的类,并给出了一个配方的任何多量子比特状态的需求的生成。所提出的方法适用于任何顺序产生方案,虽然我们专注于单光子时间仓量子比特流耦合到一个光腔中的原子发射。特别是,我们展示了如何在这样的框架内生成熟悉的量子信息态,如W,GHZ和簇态。

英文摘要:

We consider the deterministic generation of entangled multi-qubit states by the sequential coupling of an ancillary system to initially uncorrelated qubits. We characterize all achievable states in terms of classes of matrix product states and give a recipe for the generation on demand of any multi-qubit state. The proposed methods are suitable for any sequential generation-scheme, though we focus on streams of single photon time-bin qubits emitted by an atom coupled to an optical cavity. We show, in particular, how to generate familiar quantum information states such as W, GHZ, and cluster states, within such a framework.
