Title:  Some matrix and graph techniques in quantum tomography problems

Abstract:

Quantum tomography is a technique used to determine the state of a quantum system by making measurements on many identically prepared copies of that system. We discuss some recent results in the study of the quantum state tomography for quantum states and quantum systems of finite dimensional systems. The proofs of the results utilize matrix theory and graph theory. Experimental results using the IBM online quantum computers (qiskit) will be presented.

No quantum theory background is needed for the talk.
