Abstract: A circuit comprising a superconducting qubit and a resonant control system that is characterized by a resonant frequency. The resonant frequency of the control system is a function of a bias current. The circuit further includes a superconducting mechanism having a capacitance or inductance. The superconducting mechanism coherently couples the superconducting qubit to the resonant control system. A method for entangling a quantum state of a first qubit with the quantum state of a second qubit. In the method, a resonant control system, which is capacitively coupled to the first and second qubit, is tuned to a first frequency that corresponds to the energy differential between the lowest two potential energy levels of the first qubit. The resonant control system is then adjusted to a second frequency corresponding to energy differential between the lowest two potential energy levels of the second qubit.

Abstract: An optical device having an optical microsphere. Resonant electromagnetic radiation is trapped in the microsphere and manipulated with externally applied electric and magnetic fields to control polarization components of the excited energy within the microsphere. The optical microsphere can be used as a signal inverter. In the single photon regime, the optical microsphere can be used as a mechanism for entangling qubit states coded by the polarization states of whispering gallery modes excited in the microsphere. Furthermore, the device can be used as a switch for the absorption or reflection of photons in response to control photons.
