论文摘要
我们研究了由两个分布式元素电路组成的系统中的参数振荡，在单光子Kerr策略中，通过静态电容耦合。该系统的能量由两位伊斯林的哈密顿量描述，其有效耦合，其振幅和符号取决于参数泵之间的相对相。我们证明了参数振荡的二进制相之间相关性，并且可以通过调整泵相来控制相关的均衡和强度。在我们的仿真中重现了观察到的相关性，考虑到纯dephasing。目前的结果通过外部微波炉的阶段证明了汉密尔顿参数的可调节性，该参数可用于由KPO网络组成的Ising Machine硬件。
We study simultaneous parametric oscillations in a system composed of two distributed-element-circuit Josephson parametric oscillators in the single-photon Kerr regime coupled via a static capacitance. The energy of the system is described by a two-bit Ising Hamiltonian with an effective coupling whose amplitude and sign depend on the relative phase between parametric pumps. We demonstrate that the binary phases of the parametric oscillations are correlated with each other, and that the parity and strength of the correlation can be controlled by adjusting the pump phase. The observed correlation is reproduced in our simulation taking pure dephasing into account. The present result demonstrates the tunability of the Hamiltonian parameters by the phase of external microwave, which can be used in the Ising machine hardware composed of the KPO network.
