    Abstract: Achieving orthogonal control of non-orthogonal qubit parameters of a logical qubit allows for increasing the length of a qubit chain thereby increasing the effective connectivity of the qubit chain. A hybrid qubit is formed by communicatively coupling a dedicated second qubit to a first qubit. By tuning a programmable parameter of the second qubit of a hybrid qubit, an effective programmable parameter of the hybrid qubit is adjusted without affecting another effective programmable parameter of the hybrid qubit thereby achieving orthogonal control of otherwise non-orthogonal qubit parameters. The length of the logical qubit may thus be increased by communicatively coupling a plurality of such hybrid qubits together.

    Abstract: A second problem Hamiltonian may replace a first problem Hamiltonian during evolution of an analog processor (e.g., quantum processor) during a first iteration in solving a first problem. This may be repeated during a second, or further successive iterations on the first problem, following re-initialization of the analog processor. An analog processor may evolve under a first non-monotonic evolution schedule during a first iteration, and second non-monotonic evolution schedule under second, or additional non-monotonic evolution schedule under even further iterations. A first graph and second graph may each be processed to extract final states versus a plurality of evolution schedules, and a determination made as to whether the first graph is isomorphic with respect to the second graph. An analog processor may evolve by decreasing a temperature of, and a set of quantum fluctuations, within the analog processor until the analog processor reaches a state preferred by a problem Hamiltonian.

    Abstract translation: 在解决第一个问题的第一次迭代期间，第二个问题哈密尔顿算子可以在模拟处理器（例如，量子处理器）的演变期间替换第一个问题哈密尔顿算子。 在对模拟处理器进行重新初始化之后，可以在关于第一问题的第二次或进一步的连续迭代中重复这一点。 在第一次迭代期间，模拟处理器可以在第一非单调进化计划下演化，并且在甚至进一步迭代的第二非单调进化计划下进行第二非单调进化计划。 可以分别处理第一图和第二图以提取最终状态与多个进化计划，并且确定关于第一图表是否与第二图形是同构的。 模拟处理器可以通过降低模拟处理器内的温度和一组量子波动来演化，直到模拟处理器达到由问题哈密尔顿算子所优选的状态。
