We have some new preprints out on the arxiv which stem from our collaboration with Rob Spekkens at the Perimeter Institute. The first is related to a new way of operationally determining the ‘Generalized Probability Theory’ that explains experimental results; we applied this method to optical 3-level systems, which quantum mechanics would describe as qutrits.

Our new paper Experimentally Bounding Deviations From Quantum Theory in the Landscape of Generalized Probabilistic Theories by Mike Mazurek, Matt Pusey, Kevin Resch, and Rob Spekkens was published in the journal PRX Quantum. This work is a collaboration with our colleagues from the Perimeter Institute for Theoretical Physics. Abstract: Many experiments in the field of […] Our paper, Reconstructing ultrafast energy-time-entangled two-photon pulses, by JP, Sacha, and Kevin was published in PRA. Abstract: The generation of ultrafast laser pulses and the reconstruction of their electric fields is essential for many applications in modern optics. Quantum optical fields can also be generated on ultrafast timescales; however,the tools and methods available for strong […] The paper Ultrafast quantum interferometry with energy-time entangled photons by JP MacLean, John Donohue, and Kevin Resch was published in Physical Review A. Abstract: Many quantum advantages in metrology and communication arise from interferometric phenomena. Such phenomena can occur on ultrafast timescales, particularly when energy-time entangled photons are employed. These have been relatively unexplored as […] We have a new paper, Direct Characterization of Ultrafast Energy-Time Entangled Photon Pairs, by JP MacLean, John Donohue, and Kevin Resch that just appeared in Physical Review Letters. It was selected as an Editors’ Suggestion and Featured in a Synopsis in Physics. Abstract: Energy-time entangled photons are critical in many quantum optical phenomena and have […] Our paper, Quantum-coherent mixtures of causal relations, by JP MacLean, Katja Ried, Rob Spekkens and Kevin Resch was published today in Nature Communications. This work was the result of a collaboration between the Quantum Optics and Quantum Information group at the University of Waterloo (IQC/Physics) and the Perimeter Institute. Abstract: Understanding the causal influences that […] Our article, Observation of Genuine Three-photon Interference, by Sascha Agne, Thomas Kauten, Jeongwan Jin, Evan Meyer-Scott, Jeff Z. Salvail, Deny R. Hamel, Kevin J. Resch, Gregor Weihs, and Thomas Jennewein was published in Physical Review Letters. This work was a collaboration between groups at IQC and the University of Innsbruck. The paper was discussed as […] Abstract: A time lens, which can be used to reshape the spectral and temporal properties of […] Our paper, Phonon-Mediated Nonclassical Interference in Diamond, by Duncan England, Kent Fisher, Jean-Philippe MacLean, Philip Bustard, Khabat Heshami, Kevin Resch, and Benjamin Sussman was published in Physical Review Letters. This work is the result of a collaboration with Ben Sussman’s Quantum Technologies Laboratory at the National Research Council Canada. Abstract: Quantum interference of single photons […] Our article, An experimental test of noncontextuality without unphysical idealizations, by Mike Mazurek, Matt Pusey, Ravi Kunjwal, Kevin Resch, and Rob Spekkens was just published in Nature Communications. This work is the result of a collaboration between IQC and the Perimeter Institute on Experimental Quantum Foundations. Abstract: To make precise the sense in which […] |
