Experimental implementation of a four-player quantum game
Christian Schmid, Adrian P. Flitney, Witlef Wieczorek +3
Game theory is central to the understanding of competitive interactions arising in many fields, from the social and physical sciences to economics. Recently, as the definition of i…
Quantum teleportation and entanglement swapping with linear optics logic gates
Christian Schmid, Nikolai Kiesel, Ulrich K. Weber +3
We report on the usage of a linear optics phase gate for distinguishing all four Bell states simultaneously in a quantum teleportation and entanglement swapping protocol. This is d…
Experimental observation of an entire family of four-photon entangled states
Witlef Wieczorek, Christian Schmid, Nikolai Kiesel +3
A single linear optical set-up is used to observe an entire family of four-photon entangled states. This approach breaks with the inflexibility of present linear-optical set-ups us…
Discriminating multi-partite entangled states
Christian Schmid, Nikolai Kiesel, Wiesław Laskowski +3
The variety of multi-partite entangled states enables numerous applications in novel quantum information tasks. In order to compare the suitability of different states from a theor…
