Experimental demonstration of universal symmetric quantum telecloning
S. Gaertner, J. Lau, N. Kiesel +2
Quantum telecloning is a multiparty quantum communication protocol which allows quantum information broadcasting. It can be, therefore, seen as a generalization of quantum teleport…
Addendum to "Experimental demonstration of a quantum protocol for Byzantine agreement and liar detection" arXiv:0710.0290
Sascha Gaertner, Mohamed Bourennane, Christian Kurtsiefer +2
Gao et al. [Phys. Rev. Lett. 101, 208901 (2008)] have described a possible intercept-resend attack for the quantum protocol for detectable Byzantine agreement in Phys. Rev. Lett. 1…
Experimental demonstration of a quantum protocol for Byzantine agreement and liar detection
Sascha Gaertner, Mohamed Bourennane, Christian Kurtsiefer +2
We introduce a new quantum protocol for solving detectable Byzantine agreement (also called detectable broadcast) between three parties, and also for solving the detectable liar de…
Experimental demonstration of four-party quantum secret sharing
S. Gaertner, C. Kurtsiefer, M. Bourennane +1
Secret sharing is a multiparty cryptographic task in which some secret information is splitted into several pieces which are distributed among the participants such that only an au…
Witnessing multipartite entanglement
Mohamed Bourennane, Manfred Eibl, Christian Kurtsiefer +7
We present the experimental detection of genuine multipartite entanglement using entanglement witness operators. To this aim we introduce a canonical way of constructing and decomp…
Decoherence-Free Quantum Information Processing with Four-Photon Entangled States
Mohamed Bourennane, Manfred Eibl, Sascha Gaertner +3
Decoherence-free states protect quantum information from collective noise, the predominant cause of decoherence in current implementations of quantum communication and computation.…
