Quantum information science (QIS) is a pioneering field of research at the interface of physics and information science. By harnessing the unique properties of quantum mechanics to code, transmit and process information (Qbit), QIS offers significant opportunities to revolutionise information processing and communication strategies.

Quantum information protocols tend to involve more and more entangled photon pairs, for enabling advanced quantum tasks. To compensate for the low success efficiency of these protocols, one can increase the repetition rate of the emitted pairs, up to current telecom standard (40 GHz). In this context, we propose a realization of ultra-fast...

We report a telecom teleportation experiment involving narrowband entangled photons and faint laser pulses. This opens the route towards hybrid quantum nodes combining cold-atom single photon sources and entanglement-based quantum relays.

We report a realization of ultra-fast photon pair sources, specif- ically designed for efficient, long-distance, quantum relay operation. As a viable solution, our sources are capable to deliver high quality single photon pairs at high repetition rate, guaranteeing efficient operational condition for intended protocol.

We report a versatile and practical approach for generating high-quality polarization entanglement in a fully guided-wave fashion. Our setup relies on a high-brilliance type-0 waveguide generator producing paired photon at a telecom wavelength associated with an advanced energy-time to polarisation transcriber. The latter is capable of creating...

We report a versatile guided-wave approach for engineering high-quality polarization entanglement at telecom wavelengths. This scheme enables manipulating photonic bandwidths ranging from 25 MHz to 1 THz, and creating any two-photon state.

Entanglement has evolved from being a spooky interaction towards a key resource of real-life applications such as absolute secure communication. Today, quantum networking devices are commercially available, typically taking advantage of time-bin or polarisation entanglement, the latter one doubtlessly being easier to analyse thanks to...

We show how photonic entanglement can be suitably engineered on the polarization observable, opening the route towards quantum network applications.

We report a teleportation experiment involving narrowband entangled photons at 1560 nm and qubit photons at 795 nm emulated by faint laser pulses. A nonlinear difference frequency generation stage converts the 795 nm photons to 1560 nm in order to enable interference with one photon out of the pairs, i.e., at the same wavelength. The spectral...
