在相空间中模拟复杂网络:高斯玻色子采样

Simulating complex networks in phase space: Gaussian boson sampling

Peter D. Drummond, Bogdan Opanchuk, Alexander Dellios, Margaret D. Reid

摘要:

我们展示了如何在光子网络中的高斯量子态的相空间模拟允许高斯玻色子采样(GBS)量子计算机的可测量的相关性的验证。我们的结果与实验一致,高达100阶的相关性,包括退相干。我们将其扩展到超过16,000种模式,并描述如何模拟真正的多体纠缠。

英文摘要:

We show how phase-space simulations of Gaussian quantum states in a photonic network permit verification of measurable correlations of Gaussian boson sampling (GBS) quantum computers. Our results agree with experiments for up to 100-th order correlations, provided decoherence is included. We extend this to more than 16,000 modes, and describe how to simulate genuine multipartite entanglement.
