Two-mode squeezed states as Schrodinger-cat-like states
E. Oudot, P. Sekatski, F. Fröwis +2
In recent years, there has been an increased interest in the generation of superposition of coherent states with opposite phases, the so-called photonic Schrodinger-cat states. The…
Comparing different approaches for generating random numbers device-independently using a photon pair source
V. Caprara Vivoli, P. Sekatski, J. -D. Bancal +6
What is the most efficient way to generate random numbers device-independently using a photon pair source based on spontaneous parametric down conversion (SPDC)? We consider this q…
Challenging preconceptions about Bell tests with photon pairs
V. Caprara Vivoli, P. Sekatski, J. -D. Bancal +7
Motivated by very recent experiments, we consider a scenario "à la Bell" in which two protagonists test the Clauser-Horne-Shimony-Holt (CHSH) inequality using a photon-pair source…
How difficult it is to prove the quantumness of macroscropic states?
Pavel Sekatski, Nicolas Gisin, Nicolas Sangouard
General wisdom tells us that if two quantum states are ``macroscopically distinguishable'' then their superposition should be hard to observe. We make this intuition precise and ge…
Macroscopic optomechanics from displaced single-photon entanglement
Pavel Sekatski, Markus Aspelmeyer, Nicolas Sangouard
Displaced single-photon entanglement is a simple form of optical entanglement, obtained by sending a photon on a beamsplitter and subsequently applying a displacement operation. We…
