Encoding quantum information into a set of harmonic oscillators is considered a hardware
efficient approach to mitigate noise for reliable quantum information processing. Various …

Structured waves are ubiquitous for all areas of wave physics, both classical and quantum,
where the wavefields are inhomogeneous and cannot be approximated by a single plane …

Free electrons are excellent tools to probe and manipulate nanoscale optical fields with
emerging applications in ultrafast spectromicroscopy and quantum metrology. However …

A central challenge in the emerging field of free-electron quantum optics is to achieve strong
quantum interaction and single-photon nonlinearity between a flying free electron and a …

The quantum interaction between free electrons and photons is fundamental to free-electron-

We reveal a mechanism to enhance particle-matter interactions by exploiting the pseudo-
Brewster effect of gain materials, presenting an enhancement of at least four orders of …

Long-distance quantum communication will require the use of quantum repeaters to
overcome the exponential attenuation of signal with distance. One class of such repeaters …
