  • As electronic devices move towards higher frequencies, new quantum mechanical effects become accessible. Gaury and Waintal simulate ultra-fast voltage pulses in the quantum regime and study their ability to dynamically control the relative phases of the paths in an electronic interferometer.

  • Most of the peculiar effects resulting from superconductivity have counterparts in nonsuperconducting nanoelectronic devices, but not yet in the a.c. Josephson effect. Here, the authors propose how to generate a transient version of this phenomenon in a normal conductor by abruptly changing the bias voltage.

  • Electronic excitations in low-dimensional quantum nanoelectronic devices are collective waves that are strongly affected by the Coulomb interaction. Here, the authors demonstrate that they are able to prepare these collective excitations down to the single electron level and control their propagation.

  • The development of electronic flying qubits requires the ability to generate and control single-electron excitations. Here the authors demonstrate quantum coherence of ultrashort single-electron plasmonic pulses in an electronic Mach-Zehnder interferometer, revealing a non-adiabatic regime at high frequencies.

  • Collisions between two individual electrons in a quantum nanoelectronic circuit revealed a mutual interaction fully mediated by Coulomb repulsion—an essential building block for two-qubit logic implementations with flying electrons.

  • Surface acoustic waves are promising candidates to convey flying qubits through semiconductor circuits. The authors investigate the central building block of such a circuit in an experiment and present a route to realise quantum logic gates with flying electrons that are surfing on a sound-wave.
