- Title: Quantum Entanglement in Time
- Authors: Del Rajan (Victoria University of Wellington)
- Abstract summary: This thesis provides one of the first theoretical expositions on a quantum effect known as entanglement in time.
It can be viewed as an interdependence of quantum systems across time, which is stronger than could ever exist between classical systems.
An original contribution of this thesis is the design of one of the first applications of entanglement in time.

- Abstract: In this doctoral thesis we provide one of the first theoretical expositions
on a quantum effect known as entanglement in time. It can be viewed as an
interdependence of quantum systems across time, which is stronger than could
ever exist between classical systems. We explore this temporal effect within
the study of quantum information and its foundations as well as through
relativistic quantum information. An original contribution of this thesis is
the design of one of the first applications of entanglement in time.

We show that quantum mutual information in time serves as a natural measure of correlation between timelike-separated systems.
We also show how such quantum mutual information is time-symmetric with respect to quantum Bayesian inversion.
We conclude by showing how mutual information in time yields a Holevo bound for the amount of classical information that may be extracted from sequential measurements on an ensemble of quantum states.

We show that the dependence of the quantum chaotic measure on the chaoticity of finite time trajectories can be well captured by a function that is independent of the system.
This strongly implies the universal validity of the finite time quantum-classical correspondence.

We make use of ansatz based on quantum convolutional neural networks and numerically show that it is capable of recognizing quantum phases of ground states.
The observation of non-trivial learning properties demonstrated in these benchmarks will motivate further exploration of the quantum-data learning architecture in high-energy physics.
