Quantum Complexity and Quantum Simulations of Nuclear Many-Body Systems

ORAL

Abstract

The development of quantum information has provided new perspectives on quantum many-body problems, and, in turn, is enabling the development of improved methods and algorithms for describing nuclear structure and dynamics on classical and quantum computers.

In this talk I will discuss recent works utilizing notions of quantum information, such as entanglement and non-stabilizerness (magic), to gain insight into the structure of nuclei and to guide the development of more efficient hybrid classical-quantum algorithms for the simulation of nuclear systems.
