摘要:
相干XY机(CXYM)是一种物理自旋模拟器,通过将XY自旋映射到非简并光学参量振荡器(NOPO)的连续相位上来模拟XY模型。在此,我们展示了一个大规模CXYM,通过在光纤环形腔中的高非线性光纤内利用四波混频产生10 GHz时钟时分复用的NOPO脉冲,实现了超过47,000个自旋。通过使用可变1脉冲延迟平面光波电路干涉仪实现从第i个脉冲到第(i+1)个脉冲的单向耦合,我们成功地将一维XY自旋网络的有效温度控制在两个数量级以内。
英文摘要:
A coherent XY machine (CXYM) is a physical spin simulator that can simulate the XY model by mapping XY spins onto the continuous phases of non-degenerate optical parametric oscillators (NOPOs). Here, we demonstrated a large-scale CXYM with >47,000 spins by generating 10-GHz-clock time-multiplexed NOPO pulses via four-wave mixing in a highly nonlinear fiber inside a fiber ring cavity. By implementing a unidirectional coupling from the i-th pulse to the (i+1)-th pulse with a variable 1-pulse delay planar lightwave circuit interferometer, we successfully controlled the effective temperature of a one-dimensional XY spin network within two orders of magnitude.
