论文摘要
我们证明了从经典随机波动的两分射全光量子模拟器中从局部噪声到全局噪声的过渡。 Qubits以参数下转换（PDC）产生的两个纠缠光子的极化程度编码，而环境则使用其空间自由度实施。高精度操纵的能力是空间光调节器和光谱PDC宽度的相关像素的数量，使我们能够从将Qubits嵌入到本地环境中到它们受到相同全局噪声的情况。我们通过监视两分国家的破坏来目睹过渡。
We demonstrate the transition from local to global noise in a two-qubit all-optical quantum simulator subject to classical random fluctuations. Qubits are encoded in the polarization degree of freedom of two entangled photons generated by parametric down-conversion (PDC) while the environment is implemented using their spatial degrees of freedom. The ability to manipulate with high accuracy the number of correlated pixels of a spatial-light-modulator and the spectral PDC width, allows us to control the transition from a scenario where the qubits are embedded in local environments to the situation where they are subject to the same global noise. We witness the transition by monitoring the decoherence of the two-qubit state.
