Talk delivered for the Relativistic Quantum Information-North 2022 Online.
Abstract:
Studying the entanglement structure of a quantum field theory provides rich insight into its information-theoretic properties. However, the tools presently available to evaluate entanglement in quantum fields can only be feasibly applied in a small subset of physical systems, such as vacuum ground states or systems with holographic descriptions. Thus, we still lack a method of computing a true entanglement measure which is both practical and broadly applicable. The solution may come in the form of particle detector models, a class of systems which serve as probes of the quantum field, and provide such benefits as being inherently regularized and more directly connected to experimental protocols. As a first proof-of-concept, we are working to reproduce the area laws characteristic of local quantum field theories using detector models. In this talk, I will share initial results and future directions of this exploration.
