Sources of non‐classical light are of paramount importance for future applications in
quantum science and technology such as quantum communication, quantum computation …

We present a second quantization description of frequency-based continuous variables
quantum computation in the subspace of single photons. For this, we define frequency and …

We report on the generation of an indistinguishable heralded single-photon state, using
highly nondegenerate spontaneous parametric downconversion (SPDC). Spectrally …

Quadratic light-matter interactions are nonlinear couplings such that quantum emitters
interact with photonic or phononic modes exclusively via the exchange of excitation pairs …

In an experiment reported recently (Mosley et al 2008 Phys. Rev. Lett. 100 133601), we
demonstrated that, through group velocity matched parametric downconversion, heralded …

We demonstrate a technique for characterizing two-photon quantum states based on joint
temporal cor<? format?> relation measurements using time-resolved single-photon …

We study the fundamental limits of the precision of estimating parameters of a quantum
matter system when it is probed by a traveling pulse of quantum light. In particular, we focus …

It depends. For a single molecule interacting with one mode of a biphoton probe, we show
that the spectroscopic information has three contributions, only one of which is a genuine …

We extensively discuss the Hong–Ou–Mandel experiment by taking an original phase-
space-based perspective. For this, we analyze time and frequency variables as quantum …

Photon pairs produced by the pulse-pumped nonlinear parametric processes have been a
workhorse of quantum information science (QIS). Engineering the spectral property of …
