The theory of noise, measurement, and amplification in quantum information processing devices deviates substantially from its counterparts in conventional engineering disciplines. Quantum-mechanical systems exhibit distinctly different behavior compared to their classical counterparts, necessitating a revised theoretical framework.

In this talk, I will provide a mathematical viewpoint on the theory of quantum noise. As an illustrative example, I will study a quantum-information-theorist's version of a classical Markov chain and demonstrate how the theory deviates from classical expectations.

This is a Quantum Information Math RIT Seminar which is part of the larger MathQuantum RTG program at UMD.
