论文摘要
我们提出了一种见证在高斯州的两个连续变化系统之间纠缠的方法。它的关键成分是从原始的空间分离系统转移到两个空间分离的量子位。这些量表最初处于纯产品状态,因此通过检测我们目睹两个原始系统之间纠缠的Qubits之间的纠缠。这种方法大大简化了复杂系统中的纠缠。
We propose a method to witness entanglement between two continuous-variable systems in a Gaussian state. Its key ingredient is a local lossy state transfer from the original spatially separated systems onto two spatially separated qubits. The qubits are initially in a pure product state, therefore by detecting entanglement between the qubits we witness entanglement between the two original systems. This method greatly simplifies entanglement witnessing in complex systems.
