In this report we review the present state of the art of the control of propagating quantum
states at the single-electron level and its potential application to quantum information …

The progress of charge manipulation in semiconductor-based nanoscale devices opened
up a novel route to realise a flying qubit with a single electron. In the present review, we …

Nearly 30 years ago, two-photon interference was observed, marking the beginning of a
new quantum era. Indeed, two-photon interference has no classical analogue, giving it a …

The fastest possible collective response of a quantum many-body system is related to its
excitations at the highest possible energy. In condensed matter systems, the time scale for …

Two-particle interference is a fundamental feature of quantum mechanics, and is even less
intuitive than wave–particle duality for a single particle. In this duality, classical concepts …

The complete knowledge of a quantum state allows the prediction of the probability of all
possible measurement outcomes, a crucial step in quantum mechanics. It can be provided …

The nonlinear response of a beam splitter to the coincident arrival of interacting particles
enables numerous applications in quantum engineering and metrology. Yet, it poses …

The edge channels of the quantum Hall effect provide one dimensional chiral and ballistic
wires along which electrons can be guided in an optics‐like setup. Electronic propagation …

Electron flying qubits are envisioned as potential information links within a quantum
computer, but also promise—like photonic approaches—to serve as self-standing quantum …

A series of recent experiments have shown that collision of ballistic electrons in
semiconductors can be used to probe the indistinguishability of single-electron …
