We are seeking a candidate with a proven international scientific reputation, with a wide range of skills and knowledge, including a very good understanding of quantum optics and quantum information physics. Expertise in hybrid quantum systems (such as NV centers, ultra-cold atoms or trapped ions, quantum memories, superconducting qubits, or opto-mechanical systems) is desired. Moreover, the candidate’s research should combine fundamental physics aspects and applications in quantum information…

Heralded photon amplification (HPA) is a teleportation-based protocol that has been proposed as a means to overcome transmission loss for DI-QKD. In a recent Quantum Science and Technology paper we show how HPA for path entangled states and characterise the entanglement before and after loss by exploiting a recently developed displacement-based detection scheme. We demonstrate that by exploiting HPA we are able to reliably maintain high fidelity entangled states over loss-equivalent distances…

Quantum Vision Project Accepted Ours and five other groups, all from the University of Geneva, have been awarded a Sinergia multidisciplinary Swiss national project. The aim of this ambitious project is to investigate whether our senses, and especially our vision, are sensitive to purely quantum phenomena, like quantum interferences and photon entanglement.

The decision has been officially taken in November. Official website: http://cms.unige.ch/sciences/physique/la-section/p... His thesis is available…
Demonstration of EPR Steering Using Single-Photon Path Entanglement and Displacement-Based Detection
Oct 3, 2016, 1:10 PM
Our paper demonstrating the violation of an Einstein-Podolsky-Rosen steering inequality developed for single-photon path entanglement with displacement-based detection has been published in Physical Review Letters. We use a high-rate source of heralded single-photon path-entangled states, combined with high-efficiency superconducting-based detectors, in a scheme that is free of any post-selection and thus immune to the detection loophole. This result conclusively demonstrates single-photon…
