Josephson frequency

The Josephson frequency refers to the oscillation of electrical voltage across a type of junction made between two superconducting materials. This phenomenon occurs when a small supercurrent passes through the junction, creating a specific frequency of alternating current. The frequency is directly related to the amount of voltage applied, meaning that as the voltage increases, the oscillation frequency also increases. This effect is fundamental in quantum electronics and has applications in highly sensitive measurement devices, like qubits in quantum computing and in developing super-sensitive magnetometers.
