At temperatures near absolute zero, some metals lose their electrical resistance and become superconductors of electricity. Prof. Lesley Cohen of Imperial College London describes how superconductivity was discovered, and its underlying quantum nature with electric current carried by particles behaving coherently. She describes the longstanding search for superconductivity at room temperature; and how low-temperature superconducting qubits are leading the race to build a quantum computer.
