Long Distance Nonlocality Test with Entanglement Swapping and Displacement-Based Measurements
Anders J. E. Bjerrum, Jonatan B. Brask, Jonas S. Neergaard-Nielsen +1
We analyze an all-optical setup which enables Bell-inequality violation over long distances by exploiting probabilistic entanglement swapping. The setup involves only two-mode sque…
Autonomous Quantum Refrigerator in a Circuit-QED Architecture Based on a Josephson Junction
Patrick P. Hofer, Martí Perarnau-Llobet, Jonatan Bohr Brask +3
An implementation of a small quantum absorption refrigerator in a circuit QED architecture is proposed. The setup consists of three harmonic oscillators coupled to a Josephson unct…
Nonlocality of and Dicke states subject to losses
Tomer Jack Barnea, Gilles Pütz, Jonatan Bohr Brask +3
We discuss the nonlocality of the and the Dicke states subject to losses. We consider two noise models, namely loss of excitations and loss of particles, and investigate how mu…
A unifying framework for relaxations of the causal assumptions in Bell's theorem
Rafael Chaves, Richard Kueng, Jonatan Bohr Brask +1
Bell's Theorem shows that quantum mechanical correlations can violate the constraints that the causal structure of certain experiments impose on any classical explanation. It is th…
Optimal randomness generation from optical Bell experiments
Alejandro Máttar, Paul Skrzypczyk, Jonatan Bohr Brask +2
Genuine randomness can be certified from Bell tests without any detailed assumptions on the working of the devices with which the test is implemented. An important class of experim…
Bell tests for continuous variable systems using hybrid measurements and heralded amplifiers
Jonatan Bohr Brask, Nicolas Brunner, Daniel Cavalcanti +1
We present Bell tests for optical continuous variable systems, combining both hybrid measurements (i.e. measuring both particle and wave aspects of light) and heralded amplifiers.…
