摘要

变分量子算法是混合量子经典方法,因其利用近期量子硬件计算优势的潜力而被广泛研究。在这项工作中,我们在室温下成功地在硅光子集成电路上执行了两种变分量子算法:氢分子的变分量子本征解和半素数的变分量子分解。在我们的可重构硅光子电路中,利用四个相同的基于自发四波混合的集成光子对源制备了两个路径纠缠的ququt,其相关性为制备通用试态提供了资源。这标志着在集成光子对源的光子量子模拟器上首次演示变分量子算法。

Four-qubit variational algorithms in silicon photonics with integrated entangled photon sources

Four-qubit variational algorithms in silicon photonics with integrated entangled photon sources

Variational quantum algorithms are hybrid quantum-classical approaches extensively studied for their potential to leverage near-term quantum hardware for computational advantages. In this work, we successfully execute two variational quantum algorithms on a silicon photonic integrated circuit at room temperature: a variational quantum eigensolver for the Hydrogen molecule and a variational quantum factorization for semiprime numbers. In our reconfigurable silicon photonic circuit, four identical spontaneous-four-wave-mixing-based integrated photon pair sources are used to prepare two path-entangled ququarts, whose correlation gives rise to the resource for generic trial states’ preparation. This marks a first demonstration of variational quantum algorithms on a photonic quantum simulator with integrated photon pair sources.
