Quantum Sensors and Metrology
A Josephson junction is a quantum device made up of two superconductors separated by a thin insulating barrier, allowing for the tunneling of Cooper pairs between the superconductors. This phenomenon enables the junction to exhibit unique electrical properties, such as the ability to control supercurrent with an applied voltage, which is foundational in the operation of various superconducting devices, including Superconducting Quantum Interference Devices (SQUIDs). The interplay between quantum mechanics and superconductivity within a Josephson junction opens up fascinating applications in metrology and sensing technologies.
