Prof. Yueh-Nan Chen (Dep. of Physics, NCKU, and Center Scientist of NCTS) and his student collaborate with Prof. Franco Nori ( Riken , Japan ) on the topics of non-Markovianity and temporal steering. They introduce and discuss a measure of temporal steering, termed the temporal steerable weight, and show that it can be used as kernel for a measure of non-Markovianity. They give both a proof of this and a range of practical examples showing how it can be implemented in existing experiments, and how it fairs against other, alternative measures of non-Markovianity. This is the first time the concepts of steering and non-Markovian channels have been combined, and they believe these results will be of interest to researchers both in quantum information and those in the field of open quantum systems.
