Project Details
Description
Robust quantum standard for the electric current based on superconducting nanowires.
When cooled below their critical temperature, superconducting nanowires with extremely small radii display behaviour contrary to their nature. Portions of the nanowire exhibit energy fluctuations that instantaneously resist current. Known as quantum phase slips, this phenomenon could be used as the dynamic equivalent quantum standard for voltage, which today is realised by arrays of Josephson junctions. The EU-funded project QUANTUM E-LEAPS project will exploit this quantum phenomenon occurring in superconducting nanowires to develop a WAY TO REALIZE a robust and easy-to-use universal quantum standard for the electric current on a single chip.
