Simple and tight monogamy relations for a class of Bell inequalities
Remigiusz Augusiak
Physical principles constraints the way nonlocal correlations can be distributed among distant parties in a Bell-type experiment. These constraints are usually expressed by monogam…
Relativistic electron wave packets carrying angular momentum
Iwo Bialynicki-Birula, Zofia Bialynicka-Birula
There are important differences between the nonrelativistic and relativistic description of electron beams. The orbital angular momentum quantum number cannot be used to specify th…
Nuclear Numerical Range and Quantum Error Correction Codes for non-unitary noise models
Patryk Lipka-Bartosik, Karol Życzkowski
We introduce a notion of nuclear numerical range defined as the set of expectation values of a given operator among normalized pure states, which belong to the nucleus of an au…
On the tightness of correlation inequalities with no quantum violation
Ravishankar Ramanathan, Marco Túlio Quintino, Ana Belén Sainz +2
We study the faces of the set of quantum correlations, i.e., the Bell and noncontextuality inequalities without any quantum violation. First, we investigate the question whether ev…
Minimal model for spontaneous quantum synchronization
Claudia Benedetti, Fernando Galve, Antonio Mandarino +2
We show the emergence of spontaneous synchronization between a pair of detuned quantum oscillators within a harmonic network. Our model does not involve any nonlinearity, driving,…
