Flux qubit

A flux qubit is a tiny superconducting circuit used in quantum computing that stores information in magnetic flux—essentially, the magnetic field passing through it. Unlike traditional bits that are either 0 or 1, flux qubits can exist in a superposition of these states simultaneously, thanks to quantum mechanics. This allows quantum computers to perform complex calculations more efficiently. The flux qubit's behavior relies on superconductivity and quantum tunneling, making it a key component in developing scalable, powerful quantum processors.
