Abstract Quantum communication has seen rapid progress towards practical large-scale networks, with quantum key distribution (QKD) spearheading this development. While fibre-based systems have been shown to be well suited for metropolitan scales, sui

Quantum communication systems can be synchronized using data patterns, precise oscillators, or pulsed lasers. We demonstrate an alternative approach that uses time-bin quanta as a reference for synchronizing low-cost oscillators down to timing uncert

Conference on Lasers and Electro-Optics.
A recent holography technique based on induced coherence has been introduced. The technique uses photon pairs wherein one of them illuminates the object, and its partner is detected. The photon illuminating the object is never detected. Here we prese

The imaging technique presented here demonstrates the feasibility of a novel approach to allow in-vivo imaging at extreme spectral ranges with enhanced resolution and ~ms acquisition times. This technique is based on the concept of induced coherence,

Single photon holographic methods would aid several applications that raised with recent advances in quantum technologies. Our method records single photon holograms without detecting the photon itself thanks to the concept of induced coherence. ©20
