Experimental Quantum Cryptography with Qutrits

Simon Groeblacher, Thomas Jennewein, Alipasha Vaziri +2

We produce two identical keys using, for the first time, entangled trinary quantum systems (qutrits) for quantum key distribution. The advantage of qutrits over the normally used b…

A Bell Theorem Without Inequalities for Two Particles, Using Inefficient Detectors

Daniel Greenberger, Michael Horne, Anton Zeilinger +1

We again consider (as in a companion paper) an entangled two-particle state that is produced from two independent down-conversion sources by the process of "entanglement-swapping",…

A Bell Theorem Without Inequalities for Two Particles, Using Efficient Detectors

Daniel M. Greenberger, Michael Horne, Anton Zeilinger

We consider an entangled two-particle state that is produced from two independent down-conversion sources by the process of "entanglement-swapping", so that the particles have neve…

Experimental Entangled Entanglement

Philip Walther, Kevin J. Resch, Caslav Brukner +1

All previous tests of local realism have studied correlations between single-particle measurements. In the present experiment, we have performed a Bell experiment on three particle…

Experimental violation of a cluster state Bell inequality

Philip Walther, Markus Aspelmeyer, Kevin J. Resch +1

Cluster states are a new type of multiqubit entangled states with entanglement properties exceptionally well suited for quantum computation. In the present work, we experimentally…

Local Conversion of Greenberger-Horne-Zeilinger States to Approximate W States

P. Walther, K. J. Resch, A. Zeilinger

Genuine 3-qubit entanglement comes in two different inconvertible types represented by the Greenberger-Horne-Zeilinger (GHZ) state and the W state. We describe a specific method ba…
