Patent ID: 7843209

Claim:
A superconducting quantum processor comprising: a plurality of computation qubits, wherein each computation qubit comprises a qubit loop formed by a loop of superconducting material and a compound Josephson junction that interrupts the qubit loop, the compound Josephson junction comprising a closed loop of superconducting material interrupted by at least two Josephson junctions, wherein the qubit loop and the compound Josephson junction form a closed superconducting current path, and wherein each computation qubit is configured to perform at least a portion of a quantum computation; a plurality of latching qubits, wherein each latching qubit comprises a qubit loop formed by a loop of superconducting material and a compound Josephson junction that interrupts the qubit loop, the compound Josephson junction comprising a closed loop of superconducting material interrupted by at least two Josephson junctions, wherein the qubit loop and the compound Josephson junction form a closed superconducting current path, and wherein each latching qubit is inductively coupled to at least one of a computation qubit and another latching qubit; and a clock signal input structure configured to couple clock signals to the compound Josephson junction of at least one latching qubit, wherein the clock signal input structure includes at least one superconducting inductor positioned sufficiently proximate the compound Josephson junction of the at least one latching qubit to inductively couple clock signals thereto.
