An electrical device in which two superconducting metals are separated by a thin layer of insulator, across which an electric current may flow in the absence of a potential difference. The current may be made to oscillate in proportion to an applied potential difference.‘If MgB2 does have the properties Cardwell suggests, it could be used to improve microwave devices and Josephson junctions, effectively superconducting transistors.’
- ‘The gap between the two superconducting layers in a Josephson junction is called the ‘weak link’.’
- ‘The work reported in Science creates qubits from superconducting circuit elements called Josephson junctions.’
- ‘Such a structure, called a Josephson junction, has for years been widely fabricated for superconductive electronic devices and hybrid circuits.’
- ‘‘It's not a single-issue subject like making an optical computer or a Josephson junction computer,’ said Prof Popescu.’
1960s named after Brian D. Josephson (born 1940), British physicist.
