Requirements for a loophole-free photonic Bell test using imperfect setting generators
Johannes Kofler, Marissa Giustina, Jan-Åke Larsson +1
Experimental violations of Bell inequalities are in general vulnerable to so-called "loopholes." In this work, we analyse the characteristics of a loophole-free Bell test with phot…
Delayed-choice gedanken experiments and their realizations
Xiao-song Ma, Johannes Kofler, Anton Zeilinger
The wave-particle duality dates back to Einstein's explanation of the photoelectric effect through quanta of light and de Broglie's hypothesis of matter waves. Quantum mechanics us…
On the equivalence of Clauser-Horne and Eberhard inequality based tests
Andrei Khrennikov, Sven Ramelow, Rupert Ursin +3
Recently, the results of the first experimental test for entangled photons closing the detection loophole (also referred to as the fair sampling loophole) were published (Vienna, 2…
