  • Patent number: 9385293
    Abstract: A system and method involve generating an electric field across a superconductor device having an ionic layer disposed between and separated from first and second superconductor layers by respective first and second barrier layers. The electric field may be generated by applying an input signal, such as a voltage, to the superconductor device while the device is in a superconducting state. The voltage may be below a threshold voltage for inducing ion transport within the ionic layer or may be above or below a threshold voltage for inducing ion transport from the ionic layer across an ionic layer/barrier layer interface. The ion transport may tune the potential profile and/or modulate the critical current of the superconductor device and may include quantum coherent ionic transport, Josephson tunneling, or resonant tunneling. The electric field generated across the superconductor device may alter the spin-states of the ions within the ionic layer.

  • Patent number: 9097751
    Abstract: An amplifier and method for improving linear response includes a plurality of N bi-SQUIDs. Each bi-SQUID has a non-uniform bi-SQUID parameter ?i, described by ?i=2?LiIci?0 can be defined for each bi-SQUIDs from i=1 to N, where Li is the loop inductance, ic is the critical current, and ?0 is a flux quantum for each bi-SQUID. The non-uniform bi-SQUIDs can be connected in series or in parallel to establish a Superconducting Quantum Interference Filter (SQIF) array of bi-SQUIDs. Once connected, a mutual inductance between the connected bi-SQUIDs can be established. If the mutual inductance between connected bi-SQUIDs is accounted for, careful manipulation of the critical current or the loop size, or both, of each bi-SQUID can result in extremely uniform behavior (linear response) of the SQIF when considered as a whole, even though the behavior of the element bi-SQUIDs is non-uniform (different ?i, parameters).
