I and i
TL;DR: There is, I think, something ethereal about i —the square root of minus one, which seems an odd beast at that time—an intruder hovering on the edge of reality.

TL;DR: In this paper, the quantum statistics effects of photons on free-electron-light interactions are observed, revealing a transition from quantum walk to classical random walk on the freeelectron energy ladder, and the electron walker serves as the probe in non-destructive quantum detection, measuring the second order photon-correlation g (2)(0) and higher order g ( n )(0).

TL;DR: In this paper, a method that combines electron energy gain and loss spectroscopy to provide a direct measurement of the local temperature in the nanoenvironment was proposed, where both loss and gain peaks exhibit a shift towards lower energies as the sample is heated up.

Noninvasive electron microscopy with interaction-free quantum measurements
TL;DR: In this paper, the authors proposed the use of interaction-free quantum measurements with electrons to eliminate sample damage in electron microscopy, and showed the possibility of such measurements in the presence of experimentally measured quantum decoherence rates.

Detecting nanometric displacements with optical ruler metrology
TL;DR: An optical ruler with dimensions of only a few tens of micrometers offers applications in nanometrology, nanomonitoring, and nanofabrication, particularly in the demanding and confined environment of future smart manufacturing tools.

TL;DR: This work creates and image a quasiparticle of topological plasmonic spin texture in a structured silver film, which pertains to cosmological structure creation and topological phase transitions in quantum matter and may transduce quantum information on the nano-femto scale.

Inelastic ponderomotive scattering of electrons at a high-intensity optical travelling wave in vacuum
TL;DR: In this paper, it was shown that the energy of sub-relativistic electrons is strongly modulated on the few-femtosecond timescale via the interaction with a travelling wave created in vacuum by two colliding laser pulses at different frequencies.
