superconducting quantum bits

Superconducting quantum bits, or qubits, are tiny circuits made from superconductors—materials that conduct electricity without resistance when cooled to very low temperatures. Unlike regular bits that store data as 0s or 1s, qubits can exist in multiple states simultaneously, thanks to quantum mechanics. This property allows quantum computers to perform complex calculations more efficiently than traditional computers. Superconducting qubits are popular because they are relatively easy to manufacture and manipulate using microwave signals, making them a leading platform in the development of practical quantum computing.
