A superconducting qubit is a type of quantum bit that uses the principles of superconductivity to represent quantum information. By exploiting the unique properties of superconductors, such as zero electrical resistance and the ability to sustain quantum coherence, these qubits can be manipulated and measured with high precision. Superconducting qubits play a crucial role in quantum computing and are integral to the development of quantum-limited amplifiers and detectors, as well as advancing techniques in quantum metrology and parameter estimation.
