Correlations of quantum particles help in distinguishing physical processes
Correlations of quantum particles help in distinguishing physical processes by Staff Writers Glasgow, UK (SPX) Feb 17, 2015 Communication security and metrology could be enhanced through a study of the role of quantum correlations in the distinguishability of physical processes, by researchers at the Universities of Strathclyde and Waterloo. The study authors devised a method for both precisely quantifying steering’s impact and relating it to the task of distinguishing physical processes. Dr Piani said: Quantum particles can be in a particular state known as `entangled’. We now know that steering is a crucial and real quantum effect; however, knowledge about what steering is actually useful for has remained limited. In our research, we related steering to the discrimination of physical processes, which seeks to answer questions about what happens in time to physical systems of interest, like microscopic particles.
