Abstract: In a quantum processor some couplers couple a given qubit to a nearest neighbor qubit (e.g., vertically and horizontally in an ordered 2D array), other couplers couple to next-nearest neighbor qubits (e.g., diagonally in the ordered 2D array). Couplers may include half-couplers, to selectively provide communicative coupling between a given qubit and other qubits, which may or may not be nearest or even next-nearest-neighbors. Tunable couplers selective mediate communicative coupling. A control system may impose a connectivity on a quantum processor, different than an “as designed” or “as manufactured” physical connectivity. Imposition may be via a digital processor processing a working or updated working graph, to map or embed a problem graph. A set of exclude qubits may be created from a comparison of hardware and working graphs. An annealing schedule may adjust a respective normalized inductance of one or more qubits, for instance to exclude certain qubits.

Abstract translation: 在量子处理器中，一些耦合器将给定的量子比特耦合到最近的相邻量子位（例如，在有序2D阵列中垂直和水平），其他耦合器耦合到下一个最近的相邻量子位（例如，在有序2D阵列中的对角线）。 耦合器可以包括半耦合器，以选择性地提供给定量子位与其他量子位之间的通信耦合，其可以是也可以不是最近的，或者甚至不是最近邻近的。 可调谐耦合器选择性地介入交流耦合。 控制系统可以在量子处理器上施加不同于“被设计”或“制造”的物理连接的连接。 拼版可以通过数字处理器处理工作或更新的工作图，映射或嵌入问题图。 可以从硬件和工作图的比较中创建一组排除量子位。 退火计划可以调整一个或多个量子位的相应的归一化电感，例如排除某些量子位。
