It’s then cooled to cryogenic temperatures to avoid thermal energy from disturbing the qubit’s state.
A superconducting qubit refers to an electronic circuit where energy levels assume quantum values. To develop superconducting qubits, researchers use 2D films made of superconducting material. It’s then cooled to cryogenic temperatures to avoid thermal energy from disturbing the qubit’s state. Electromagnetic coupling with microwave pulses is used to control the qubit.
