Two-photon Franson-type experiments and local realism
Sven Aerts, Paul Kwiat, Jan-Åke Larsson +1
The two-photon interferometric experiment proposed by Franson [Phys. Rev. Lett. 62, 2205 (1989)] is often treated as a "Bell test of local realism". However, it has been suggested…
Bell Theorem for Nonclassical Part of Quantum Teleportation Process
Marek Zukowski
The quantum teleportation process is composed of a joint measurement performed upon two subsystems A and B (uncorrelated), followed by a unitary transformation (parameters of which…
Faster than light Bell telephone of Michalski transmits only noise
Marek Zukowski, Dagomir Kaszlikowski
Motivated by pedagogical reasons we pinpoint the mistake in the recent claim, in quant-ph/9911016, that faster than light communication is possible.
Entanglement swapping with PDC sources
Marek Zukowski, Dagomir Kaszlikowski
We show that the possibility of distinguishing between single and two photon detection events is not a necessary requirement for the proof that recent operational realization of en…
Greenberger-Horne-Zeilinger paradoxes with symmetric multiport beam splitters
Marek Zukowski, Dagomir Kaszlikowski
In a gedankenexperiment N particles in a generalized GHZ-type beam entangled state (each particle can be in one of M beams) are fed into N symmetric 2M-port beam splitters (spatial…
Irrelevance of photon events distinguishability in a class of Bell experiments
Marek Zukowski, Dagomir Kaszlikowski, Emilio Santos
We show that the possibility of distinguishing between single and two photon detection events, usually not met in the actual experiments, is not a necessary requirement for the pro…
