The Josephson voltage standard is a precise electrical standard for voltage measurement based on the Josephson effect, a phenomenon discovered by physicist Brian D. Josephson in 1962. This effect occurs in superconducting materials, where a supercurrent can flow between two superconductors separated by a thin insulating barrier, allowing for the generation of an accurate and stable voltage.
