Description
Entanglement measures the nonclassical correlations of a quantum system and is a crucial resource in quantum information and quantum enabled technologies. We analyze the statistical properties of the bipartite entanglement of a large quantum system. By applying general methods of statistical mechanics, we introduce a fictitious temperature and a partition function and translate the problem in terms of a random matrix model. We will unveil the existence of two phase transitions: one associated with very entangled states, and the other signaling the appearance of a significant factorization in the many-body wave function. Finally, we will show how the generalization to multipartite entanglement unearths interesting links with complexity and frustration.
