论文摘要
我们提出并展示了一种非线性光学方法，以模拟最多一百万起自动的伊辛机器，并与全能连接进行了量身定制的两种和四体相互作用。它使用空间光调节器以相干激光束中小波的二元相值的形式编码和控制自旋，并在傅立叶平面的非线性晶体中模仿高阶相互作用。通过自适应反馈控制，该系统可以演变为有效的自旋构型，这些旋转构型符合具有全部连接的多体相互作用的Ising Hamiltonians的基态。我们的技术可以作为探测复杂，多体物理学的新工具，并在大数据优化，计算和分析中引起令人兴奋的应用。
We propose and demonstrate a nonlinear optics approach to emulate Ising machines containing up to a million spins and with tailored two and four-body interactions with all-to-all connections. It uses a spatial light modulator to encode and control the spins in the form of the binary phase values of wavelets in coherent laser beams, and emulates the high-order interaction with frequency conversion in a nonlinear crystal at the Fourier plane. By adaptive feedback control, the system can be evolved into effective spin configurations that well approximate the ground states of Ising Hamiltonians with all-to-all connected many-body interactions. Our technique could serve as a new tool to probe complex, many-body physics and give rise to exciting applications in big data optimization, computing, and analytics.
