摘要： A hybrid superconductor-optical quantum repeater is provided. The hybrid superconductor-optical quantum repeater comprises an optical subsystem configured to receive an optical signal via an optical channel and a superconductor subsystem coupled to the optical subsystem. The optical subsystem and superconductor subsystem are coupled to one another via a microwave transmission medium. The optical subsystem is configured to receive an optical signal via the optical channel and down-convert a photon of the optical signal to a microwave photon in a microwave output signal that is output to the superconductor subsystem via the microwave transmission medium. The superconductor subsystem stores a quantum state of the microwave photon and transmits the microwave photon along an output channel from the superconductor subsystem.

摘要： A qubit (quantum bit) circuit includes a superconducting main loop that is electrically-completed by a serially-interconnected superconducting subloop. The subloop includes two Josephson junctions. A first coil provides a first flux that couples with the main loop but not with the subloop. A second coil provides a second flux that couples with the subloop but not with the main loop.

摘要： There is provided by this invention logic and memory elements of atomic or near-atomic scale useful in computer central processing units. These elements consist of two quantum dots having opposite states and a third quantum dot situated between the two quantum dots and in physical contact with them. The third quantam dot is of a material which makes the opposite states of the first two quantum dots energetically favorable. In particular, there is provided by the invention a spin flip-flop suitable for use as electronic logic and memory in a quantum computer. The spin flip-flop is designed to have two highly stable states, encoded entirely in the arrangement of electronic spins in the structure. Switching between the two states is accomplished by fast electromagnetic pulsing generally and by optical pulsing in the case of the spin flip-flop. The two stable states are the up-down and the down-up spin states of two single electrons placed into two neighboring electronic quantum dots typically by doping or by a field effect. The operation of the device is facilitated and stabilized by the presence of a small particle or dot of an antiferromagnetic material placed between the two electronic dots, and in physical contact with both of them.

摘要： Quantum mechanical effect devices incorporate means for interrupting the two-dimensional carrier gas of a modulation doped structure to produce periodic potential variations which provide superlattice-like effects on current flowing nearby. The modulation doped structures incorporate specialized structures displaced from a current path which simultaneously confine the two-dimensional carrier gas into a quasi-one-dimensional carrier gas and subject the thus confined carrier gas and current flowing therein to superlattice-like effects by inducing periodic potential variations along the current path. The induced variations are produced by etching corrugations in the device edges or by forming them in biasing gates.
