Quantum Left-handed metamaterial with superconducting quantum interference devices
A scheme of left-handed metamaterial (LHM) composed of superconducting quantum interference devices (SQUIDs) and conducting wires is proposed. The permeability of a probe field can be smoothly tuned over a wide range with another electromagnetic (coupling) field due to quantum interference effect. Similar to electromagnetically induced transparency (EIT) of atomic systems, the absorption of the...
متن کاملActive terahertz quantum-cascade composite right/left-handed metamaterial
We report the demonstration of a composite right/left-handed (CRLH) metamaterial waveguide for terahertz quantum-cascade (QC) lasers. By incorporating gap capacitors ( 250 nm) in the top metallization of a metal-metal waveguide operating in a higher order lateral mode, we have realized a CRLH transmission line that supports traveling modes with negative effective phase indices (i.e., left-hande...
متن کاملSuperconducting quantum interference devices based on YBaCuO nanobridges
Direct current SQUIDs based on YBaCuO thin film nanobridges have been investigated. Critical current densities Jc of the devices are up to 3310 6 A/cm at T577 K and show a temperature dependence of (12T/Tc) . High values of the voltage-flux modulation are observed ~8 mV peak to peak at 77 K, 45 mV at 4.2 K!. The temperature dependence of the SQUID modulation is found to be essentially different...
متن کاملBistability and field-induced transparency in superconducting quantum interference devices
In recent years there have been many increasing activities for quantum information processing and quantum computing.1 Among the many methodologies for quantum computing, superconducting devices including Cooper pair boxes, Josephson junctions, and superconducting quantum interference devices SQUIDs Refs. 2–10 have shown great potential in realizing quantum gates and implementing quantum informa...
متن کاملThe physics of Superconducting Quantum Interference Devices (SQUIDs)
(SQUIDs) Joey Lambert December 8, 2008 Josephson junctions are interesting devices that provide a great deal of physics to research, both experimental and theoretical. The device was first proposed by Brian Josephson in short concise paper in 1962 [1], which predicts a resistance-less supercurrent that passes through the very thin insulating layer in between two macroscopic size superconductors...
