Abstract: Systems and methods are disclosed that map quantum circuits to physical qubits of a quantum computer. Techniques are disclosed to generate a graph that characterizes the physical qubits of the quantum computer and to compute the resource requirements of each circuit of the quantum circuits. For each circuit, the graph is searched for a subgraph that matches the resource requirements of the circuit, based on a density matrix. Physical qubits, defined by the matching subgraph, are then allocated to the logical qubits of the circuit.

Abstract: An electronic device includes a quantum processor including a plurality of qubits. The quantum processor runs a plurality of instances of a quantum program using a separate set of qubits from among the qubits for each instance of the quantum program. The quantum processor then sets quantum states for ancilla qubits from among the qubits based on quantum states of respective groups of associated qubits from the separate sets of qubits. The quantum processor next provides an output of the instances of the quantum program based on the quantum states of the ancilla qubits.

Abstract: An electronic device includes a quantum processor having a plurality of qubits and a processor. The processor runs a plurality of instances of a quantum program substantially in parallel on the quantum processor using a separate set of qubits from among the plurality of qubits for each instance of the quantum program. The processor then acquires an output for each instance of the quantum program from the quantum processor. The processor next uses the outputs for generating an output of the quantum program.

Abstract: A logic-memory cell includes a spin-orbit torque device having first, second and third terminals configured such that current between the second and third terminals is capable of changing a resistance between the first and second terminals. In the cell, a first transistor is connected between a logic connection line and the first terminal of the spin-orbit torque device and a second transistor is connected between the logic connection line and the third terminal of the spin-orbit torque device.
