Optical experiment to test negative probability in context of quantum-measurement selection
Junghee Ryu, Sunghyuk Hong, Joong-Sung Lee +6
Negative probability values have been widely employed as an indicator of the nonclassicality of quantum systems. Known as a quasiprobability distribution, they are regarded as a us…
Disproving hidden variable models with spin magnitude conservation
Pawel Kurzynski, Wieslaw Laskowski, Adrian Kolodziejski +3
The squares of the three components of the spin-s operators sum up to . However, a similar relation is rarely satisfied by the set of possible spin projections onto mutuall…
Entanglement conditions involving intensity correlations of optical fields: the case of multi-port interferometry
Junghee Ryu, Marcin Marciniak, Marcin Wieśniak +2
Normalized quantum Stokes operators introduced in [Phys. Rev. A {\bf 95}, 042113 (2017)] enable one to better observe non-classical correlations of entangled states of optical fiel…
Fidelity deviation in quantum teleportation
Jeongho Bang, Junghee Ryu, Dagomir Kaszlikowski
We analyze the performance of quantum teleportation in terms of average fidelity and fidelity deviation. The average fidelity is defined as the average value of the fidelities over…
