摘要： In one embodiment, the disclosure relates to a method and apparatus for controlling the energy state of a qubit by bringing the qubit into and out of resonance by coupling the qubit to a flux quantum logic gate. The qubit can be in resonance with a pump signal, with another qubit or with some quantum logic gate. In another embodiment, the disclosure relates to a method for controlling a qubit with RSFQ logic or through the interface between RSFQ and the qubit.

摘要： Systems and methods are provided for performing a quantum gate operation. A first classical control parameter is associated with a first qubit and coupled to a resonator. The first classical control parameter is transitioned from a first control value to a second control value. The first classical control parameter is returned from the second control value to the first control value via an adiabatic sweep operation, as to permit a transfer of energy between the first qubit and the resonator that causes a change in the quantum state of the qubit and resonator.

摘要： A quantum logic gate is formed from multiple qubits coupled to a common resonator, wherein quantum states in the qubits are transferred to the resonator by transitioning a classical control parameter between control points at a selected one of slow and fast transition speeds, relative to the characteristic energy of the coupling, whereby a slow transition speed exchanges energy states of a qubit and the resonator, and a fast transition speed preserves the energy states of a qubit and the resonator.

摘要： One embodiment of the invention includes a quantum system. The system includes a superconducting qubit that is controlled by a control parameter to manipulate a photon for performing quantum operations. The system also includes a quantum resonator system coupled to the superconducting qubit and which includes a first resonator and a second resonator having approximately equal resonator frequencies. The quantum resonator system can represent a first quantum logic state based on a first physical quantum state of the first and second resonators with respect to storage of the photon and a second quantum logic state based on a second physical quantum state of the first and second resonators with respect to storage of the photon.
