Displacing entanglement back and forth between the micro and macro domains
Natalia Bruno, Anthony Martin, Pavel Sekatski +3
Quantum theory is often presented as the theory describing the microscopic world, and admittedly, it has done this extremely well for decades. Nonetheless, the question of whether…
Analysis of a photon number resolving detector based on an ion Coulomb crystal inside an optical cavity
Christoph Clausen, Nicolas Sangouard, Michael Drewsen
The ability to detect single photons with high efficiency is a crucial requirement for various quantum information applications. By combining the storage process of a quantum memor…
Witnessing trustworthy single-photon entanglement with local homodyne measurements
Olivier Morin, Jean-Daniel Bancal, Melvyn Ho +5
Single-photon entangled states, i.e. states describing two optical paths sharing a single photon, constitute the simplest form of entanglement. Yet they provide a valuable resource…
Exploring Macroscopic Entanglement with a Single Photon and Coherent States
Pavel Sekatski, Nicolas Sangouard, Magdalena Stobinska +3
Entanglement between macroscopically populated states can easily be created by combining a single photon and a bright coherent state on a beam-splitter. Motivated by the simplicity…
Heralded photon amplification for quantum communication
C. I. Osorio, N. Bruno, N. Sangouard +3
Heralded noiseless amplification based on single-photon sources and linear optics is ideally suited for long-distance quantum communication tasks based on discrete variables. We ex…
What are single photons good for?
Nicolas Sangouard, Hugo Zbinden
In a long-held preconception, photons play a central role in present-day quantum technologies. But what are sources producing photons one by one good for precisely? Well, in opposi…
