A team of physicists at the University of Maryland's Joint Quantum Institute and Quantum Materials Center has achieved millisecond coherence while testing the properties of a fluxonium qubit in a quantum circuit. In their ...
Typical superconducting quantum circuits, such as qubits—basic processing units of a quantum computer, must be operated at very low temperatures, of a few 10s of millikelvin, or hundredths of a degree from absolute zero ...
