摘要： Techniques facilitating local optimization of quantum circuits are provided. In one example, a computer-implemented method comprises applying, by a device operatively coupled to a processor, respective weights to matrix elements of a first matrix corresponding to a quantum circuit according to respective numbers of quantum gates between respective pairs of qubits in the quantum circuit; transforming, by the device, the first matrix into a second matrix based on the respective weights of the matrix elements; and permuting, by the device, respective qubits in the quantum circuit according to the second matrix, resulting in a permuted quantum circuit.

摘要： A method for validation and runtime estimation of a quantum algorithm includes receiving a quantum algorithm and simulating the quantum algorithm, the quantum algorithm forming a set of quantum gates. The method further includes analyzing a first set of parameters of the set of quantum gates and analyzing a second set of parameters of a set of qubits performing the set of quantum gates. The method further includes transforming, in response to determining at least one of the first set of parameters or the second set of parameters meets an acceptability criterion, the quantum algorithm into a second set of quantum gates.

摘要： Systems, computer-implemented methods and/or computer program products are provided for facilitating error mitigation for classical data output from a classical system and/or for qubit data output from a quantum system. A system can comprise a memory that stores computer executable components and a processor that executes the computer executable components stored in the memory. The computer executable components can comprise a computation component that performs error mitigation employing less than a full set of assignment matrix elements. In one or more embodiments, the error mitigation can be performed without constructing an assignment matrix. Additionally and/or alternatively, the computer executable components can comprise a computation component that performs error mitigation employing an iterative solver using the less than a full set of assignment matrix elements as the initial input set for the iterative solver.
