Entanglement in Complex Systems

Description

Entanglement is a fundamental resource in quantum information and computation science. In this project we are interested in how entanglement is related to thermodynamic behaviour of many-body quantum systems. In particular, we are investigating a connection between entanglement and different phases of matter as well as in possible ways to utilize entanglement present in macroscopic systems.
