Join us at the Institute for Quantum Computing for a two-week introduction to the theoretical and experimental study of quantum information processing.
Existence and Uniqueness in the Quantum Marginal Problem
Joel Klassen, IQC
The quantum marginal problem asks whether a family of quantum marginals are compatible with a global quantum state. It is of central importance to a wide range of topics in both quantum many body physics and quantum information. Often it can be the case that when a family of quantum marginals are compatible with a global quantum state, that global state is unique.
