We review the concepts of temporal modes (TMs) in quantum optics, highlighting Roy
Glauber's crucial and historic contributions to their development, and their growing …

We develop a quantum theory describing the input–output properties of Josephson traveling
wave parametric amplifiers. This allows us to show how such a device can be used as a …

We propose a squeezed-light source meeting the stringent requirements of continuous-

We present a new method for the spectral characterization of pulsed twin-beam sources in
the high-gain regime, using cascaded stimulated emission. We show an implementation of …

A bright squeezed vacuum (BSV) is a nonclassical macroscopic state of light, which is
generated through high-gain parametric down-conversion or four-wave mixing. Although the …
