按需接收混合纠缠态和CV纠缠态

Receipt of hybrid entangled and CV entangled states on demand

Sergey A. Podoshvedov, Mikhail S. Podoshvedov

摘要:

我们提出了一种新的方法来产生纠缠态,混合和完全由连续变量(CV)状态。在任意分束器上,单模压缩真空与离域单光子混合,并记录辅助模下的测量结果。在辅助模式下测量任何事件都会产生纠缠态。负性被用作纠缠的度量。在一定的初始条件下,条件态变得尽可能纠缠。引入了新类型的CV状态。这种方法可以扩展到实现高复杂度的量子网络。

英文摘要:

We propose a new approach to the generation of entangled states, both hybrid and consisting exclusively of continuous variable (CV) states. A single mode squeezed vacuum is mixed with a delocalized single photon on arbitrary beam splitter (BS) with subsequent registration of some measurement outcome in auxiliary mode. The entangled states are generated whenever any event is measured in auxiliary mode. Negativity is used as a measure of entanglement. Under certain initial set conditions, the conditioned state becomes as entangled as possible. New types of CV states are introduced. This approach can be expanded to implement a high complexity quantum network.
