Temporal Quantum Steering
Abstract
Quantum mechanics contains a range of stunning and non-intuitive phenomena, including non-local spatial correlations. Our goal in this project is to investigate in what ways temporal correlations, in comparison to spatial, in quantum mechanics are important, and how these could be used as a powerful quantum resource. We will base this research on a full investigation of a new type of quantum temporal correlation, called temporal steering which we pioneered recently. In essence, temporal steering allows us to identify how much influence the quantum nature of measurements in the past have on the future. This is thought to be to be the power behind certain quantum cryptography techniques and also underlie a refined understanding of quantum causality. Recently, we did the first theoretical and experimental investigations of this stunning phenomenon. However, a complete investigation of this quantum effect is necessary as it will assist us to understand in what ways we can use temporal steering in quantum technologies (e.g. quantum cryptography and quantum sensing), which are unobtainable in classical physics. We also plan to explore potential quantum sensing applications. In addition, from the perspective of fundamental physics, this research will help understand how temporal correlations can be used to distinguish alternative theories to describe quantum phenomena. This proposal includes a list of about 20 joint Taiwan-Japan publications, which prove that this collaboration has a solid track record. The proposal is on a cutting-edge area of research which we are pioneering now. This research topic is still in its very early stages of creation.
