Congratulations to Prof. Gilad Gour, Dr. Carlo Maria Scandolo, and the former undergraduate students John Burniston and Michael Grabowecky on their article "Necessary and sufficient conditions on measurements of quantum channels" published in the Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences 476: 20190832.

Technical abstract: Quantum supermaps are a higher-order generalization of quantum maps, taking quantum maps to quantum maps. It is known that any completely positive, trace non-increasing (CPTNI) map can be performed as part of a quantum measurement. By providing an explicit counterexample we show that, instead, not every quantum supermap sending a quantum channel to a CPTNI map can be realized in a measurement on quantum channels. We find that the supermaps that can be implemented in this way are exactly those transforming quantum channels into CPTNI maps even when tensored with the identity supermap. We link this result to the fact that the principle of causality fails in the theory of quantum supermaps.

Congratulations! Prof. Paul Barclay won the 2019 CAP Herzberg Medal.
