Mechanical systems prepared in quantum non-Gaussian states constitute a new advanced
class of phenomena breaking the laws of classical physics. Specifically, such mechanical …

Gaussian states have played an important role in the physics of continuous-variable
quantum systems. They are appealing for the experimental ease with which they can be …

True on-demand high-repetition-rate single-photon sources are highly sought after for
quantum information processing applications. However, any coherently driven two-level …

Quantum non-Gaussian states of photons and phonons are conclusive and direct witnesses
of higher-than-quadratic nonlinearities in optical and mechanical processes. Moreover, they …

Single atoms or atom-like emitters are the purest source of single photons, they are
intrinsically incapable of multi-photon emission. To demonstrate this degree of photon …

Narrowband single photons that couple well to atomic ensembles could prove essential for
future quantum networks, but the efficient generation of such photons remains an …

Engineering the quantum states of freely propagating light is of paramount importance for
quantum technologies. As yet, the experimental generation of photonic states with negative …

We report a measurement workflow free of systematic errors consisting of a reconfigurable
photon-number-resolving detector, custom electronic circuitry, and faithful data-processing …

Light is an essential tool for connections between quantum devices and for diagnostic
processes in quantum technology. Both applications deal with advanced nonclassical states …

In this paper, we present a detailed, all optical study of the influence of different excitation
schemes on the indistinguishability of single photons from a single InAs quantum dot. For …
