Knowing the properties of single photons produced in a Spontaneous Parametric Down-Conversion (SPDC) source can be crucial for specific applications and uses. In particular, the spectral properties are of key relevance. Here, we investigate a commerc

Incompatible observables underlie pillars of quantum physics such as contextuality and entanglement. The Heisenberg uncertainty principle is a fundamental limitation on the measurement of the product of incompatible observables, a 'joint' measurement

We examine the precision limits of Hong-Ou-Mandel (HOM) timing measurements, as well as precision limits applying to generalized two-photon measurements. As a special case, we consider the use of two-photon measurements using photons with variable ba

We examine the precision limits of Hong-Ou-Mandel interferometry-based timing measurements using the Cramér-Rao bounds. We show how to adapt the method for realistic sources of photon pairs involving unequal mode bandwidths and nonmaximal frequency

Applications across photonics require transformations of optical spatial modes. We report an experimental scheme to implement arbitrary transformations on a two-beam array in a reconfigurable setup.

We implement a theoretical proposal by Massar and Popescu to demonstrate more efficient quantum state tomography using collective measurements. To do so, we project onto non-maximally entangled polarization states of two photons from the ensemble.

The concept that light comes in discrete units of energy, the quantum of light named photon, is a cornerstone of Quantum Physics. Current technology allow experimentalists to generate, manipulate and detect photons in ways only imaginable for the ear

Applications across photonics require transformations of optical spatial modes. Utilizing a discrete set of phase masks and free space propagation, we experimentally demonstrate general transformations on a beam array.
