摘要： A method for quantum computing with a quantum system comprising a first energy level, a second energy level, and a third energy level. The first energy level and said second energy level are capable of being degenerate with respect to each other. In the method a signal is applied to the quantum system. The signal has an alternating amplitude at an associated frequency such that (i) the frequency of the signal correlates with an energy level separation between the first energy level and the third energy level or (ii) the frequency of the signal correlates with an energy level separation between the second energy level and the third energy level. The signal induces an oscillation in the state of the quantum system between the first energy level and the second energy level.

摘要： A method for quantum computing using a quantum system comprising a plurality of qubits is provided. The system can be in any one of at least two configurations at any given time including one characterized by an initialization Hamiltonian HO and one characterized by a problem Hamiltonian HP. The problem Hamiltonian HP has a ground state. Each respective first qubit in the qubits is arranged with respect to a respective second qubit in the qubits such that they define a predetermined coupling strength. The predetermined coupling strengths between the qubits in the plurality of qubits collectively define a computational problem to be solved. In the method, the system is initialized to HO and is then adiabatically changed until the system is described by the ground state of the problem Hamiltonian HP. Then the state of the system is read out by probing an observable of the σX Pauli matrix operator.

摘要： A first qubit having a superconducting loop interrupted by a plurality of Josephson junctions is provided. Each junction interrupts a different portion of the superconducting loop and each different adjacent pair of junctions in the plurality of Josephson junctions defines a different island. An ancillary device is coupled to the first qubit. In a first example, the ancillary device is a readout mechanism respectively capacitively coupled to a first and second island in the plurality of islands of the first qubit by a first and second capacitance. Quantum nondemolition measurement of the first qubit's state may be performed. In a second example, the ancillary device is a second qubit. The second qubit's first and second islands are respectively capacitively coupled to the first and second islands of the first qubit by a capacitance. In this second example, the coupling is diagonal in the physical basis of the qubits.
