Our paper, Experimental Bound Entanglement?, by Jonathan Lavoie, Rainer Kaltenbaek, Marco Piani, and Kevin Resch was published in Nature Physics. This work comments on a claim of experimental bound entanglement published late last year in the same journal. Concluding paragraph of our comment: Undistillability is the one property that makes an […] Our paper Minimum-error discrimination of entangled quantum states by Yang Lu, Nick Coish, Rainer Kaltenbaek, Deny Hamel, Sarah Croke, and Kevin Resch was published today in Physical Review A. […] Experimental Bound Entanglement in a Four-Photon State by Jonathan Lavoie, Rainer Kaltenbaek, Marco Piani, and Kevin Resch was published today in Physical Review Letters. Bound entanglement is central to many exciting theoretical results in quantum information processing, but has thus far not been experimentally realized. In this work, we consider a […] Direct generation of photon triplets using cascaded photon-pair sources by Hannes Hübel, Deny Hamel, Sven Ramelow, Alessandro Fedrizzi, Kevin Resch, and Thomas Jennewein was published today in Nature. Parametric down-conversion is the most common source of entangled photon pairs. It uses a nonlinear optical process to split a pump photon, typically […] Experimental Feedback Control of Quantum Systems Using Weak Measurements was published in Physical Review Letters. This experiment was performed in Andrew White’s group at the University of Queensland. The work is the result of a collaboration involving researchers from Australia (Griffith U, U. Queensland, U. Sydney), the United Kingdom (U. Bristol), France (Institute […] Our paper, Derivation and experimental test of fidelity benchmarks for remote preparation of arbitrary qubit states, was published in Physical Review A. This work was done in collaboration with Norbert Lütkenhaus at IQC. […] Our article, Cluster-State Quantum Computing Enhanced by High-Fidelity Generalized Measurements, was published in Physical Review Letters. This work was done with Terry Rudolph at Imperial College and Gregor Weihs at the University of Innsbruck. We introduce and implement a technique to extend the quantum computational power of cluster states by replacing […] Automatic dispersion cancellation is one of the hallmark features of quantum interference, but does it really need any quantum resources? In this paper we demonstrate a new interference technique, called chirped-pulse interferometry, which exhibits automatic dispersion cancellation without entanglement or any quantum effects. No longer constrained to running two photons at a time, […] |
