Quantum communication aims at generating, distributing and storing qubits between distant locations, in view of implementing actual quantum networks. Coherent, efficient and reversible storage of photonic states in atomic memories is thus necessary and represents a major challenge in quantum information science. Several storage medium, such as...

En Communication Quantique, la distribution fibrée de l'information quantique entre deux sites distants passe par la construction de véritables réseaux quantiques. Dans ce contexte, le stockage cohérent, efficace et réversible d'états quantiques de la lumière dans des mémoires atomiques représente actuellement un enjeu majeur. Nous présentons...

During the last decade, quantum entanglement has paved the way out to of the lab modern applications such as quantum computation and communication. Today, small scale quantum networks exist already, but they are limited to a few 100 km distance, due to intrinsic fiber transmission losses and non perfect detectors. These networks are typically...

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...
