摘要： Quantum circuits include quantum gates that require a certain amount of physical resources. It is desirable to reduce the number of certain quantum gates in order to improve the hardware efficiency of a quantum circuit. A system and a method are provided for synthesizing a quantum circuit that includes the operations of determining an ordered set or vector of phase coefficients and specifying a linear permutation. The operations also include determining a sequence of CNOT and Rz gates using the set of phase coefficients and the linear permutation, such that the number of Rz gates is reduced.

摘要： An asynchronous approach to implementing a quantum algorithm can reduce dead time of a quantum information processing unit (QIPU). Multiple parameter sets are determined for a quantum program by a controller and the QIPU is instructed to execute the quantum program for the parameter sets. Results from each program execution are returned to the controller. After one or more results are received, the controller determines an updated parameter set while the QIPU continues executing the quantum program for the remaining parameter sets. The QIPU is instructed to execute the quantum program for the updated parameter set (e.g., immediately, after a current program execution, or after the remaining parameter sets are processed). This asynchronous approach can result in the QIPU having little or no dead time, and thus can make more efficient use of the QIPU.
