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 …

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 …

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

In this work, we present the inverted harmonic oscillator (IHO) Hamiltonian as a paradigm to
understand the quantum mechanics of scattering and time-decay in a diverse set of physical …

In quantum nanoelectronics, time-dependent electrical currents are built from few
elementary excitations emitted with well-defined wavefunctions. However, despite the …

Scattering or tunneling of an electron at a potential barrier is a fundamental quantum effect.
Electron-electron interactions often affect the scattering, and understanding of the interaction …

We revisit the arguments underlying two well-known arrival-time distributions in quantum
mechanics, viz., the Aharonov–Bohm–Kijowski (ABK) distribution, applicable for freely …

We study the decoherence and relaxation of a single elementary electronic excitation
propagating in a one-dimensional chiral conductor. Using two-particle interferences in the …

A method for characterising the wave-function of freely-propagating particles would provide
a useful tool for developing quantum-information technologies with single electronic …
