Bell's inequalities detect efficient entanglement
Antonio Acin, Nicolas Gisin, Lluis Masanes +1
We review the status of Bell's inequalities in quantum information, stressing mainly the links with quantum key distribution and distillation of entanglement. We also prove that fo…
Experimental realization of entangled qutrits for quantum communication
R. T. Thew, A. Acin, H. Zbinden +1
We have experimentally realized a technique to generate, control and measure entangled qutrits, 3-dimensional quantum systems. This scheme uses spontaneous parametric down converte…
Quantum cryptography with fewer random numbers
N. Gisin
We prove that in the BB84 quantum cryptography protocol Alice and Bob do not need to make random bases-choice for each qubit: they can keep the same bases for entire blocks of qubi…
Security bounds in Quantum Cryptography using d-level systems
Antonio Acin, Nicolas Gisin, Valerio Scarani
We analyze the security of quantum cryptography schemes for -level systems using 2 or maximally conjugated bases, under individual eavesdropping attacks based on cloning m…
Quantum communications with time-bin entangled photons: long distance quantum teleportation and quantum repeaters
N. Gisin, I. Marcikic, H. de Riedmatten +2
Using 2 km of standard telecom optical fibres, we teleport qubits carried by photons of 1310 nm wavelength to qubits in another lab carried by a photons of 1550 nm wavelength. The…
