A few decades ago, quantum optics stood out as a new domain of physics by exhibiting
states of light with no classical equivalent. The first investigations concerned single photons …

The time-frequency degree of freedom is a powerful resource for implementing high-
dimensional quantum information processing. In particular, field-orthogonal pulsed temporal …

We report the experimental realization and characterization of one 60-mode copy and of two
30-mode copies of a dual-rail quantum-wire cluster state in the quantum optical frequency …

High-dimensional entanglement is a valuable resource for quantum communication, and
photon pairs entangled in orbital angular momentum (OAM) are commonly used for …

Over the last two decades, integrated photonics has profoundly revolutionized the domain of
quantum technologies. The ongoing second quantum revolution stands as a timely …

Multimode quantum resources or states, in which quantum correlations are shared and
distributed among multiple parties, are important not only for fundamental tests of quantum …

Directly modulated semiconductor lasers are widely used, compact light sources in optical
communications. Semiconductors can also be used to generate nonclassical light; in fact …

We study the possibility of producing and detecting continuous variable cluster states in an
extremely compact optical setup. This method is based on a multi-pixel homodyne detection …

We study the Bloch-Messiah reduction of parametric down-conversion of light in the pulsed
regime with a nondegenerate phase matching providing generation of twin beams. We find …

We study the quantum correlations induced by spontaneous parametric down-conversion of
a frequency comb. We derive a theoretical method to find the output state corresponding to a …
