  • Josephson junctions are used for SQUIDs, voltage standards, and superconducting qubits. These applications are located at one corner of the device parameter space. Here, the authors shed light on the other corner and show the quantized current of Josephson junctions — dual to the quantized voltage.

  • Direct observation of the physical dual a.c. Josephson effect, a series of quantized current steps in a superconducting nanowire, is reported and may offer a way to establish new metrological standards for currents.

  • Attosecond spectroscopy enables the study and manipulation of electron dynamics in solid state samples, enabling the potential realisation of ultrafast optoelectronics. Here, the authors report the generation and control of light-induced quantum tunnelling currents in graphene phototransistors with sub-femtosecond switching times under ambient conditions.
