The dynamics of open quantum systems, i.e., of systems interacting with an environment, forms the basis of numerous active areas of research. One approach to modeling open quantum system is via a Collision Model in which the environment is itself assumed to be composed of many small quantum systems (ancillas) which interact with the target system sequentially. In this seminar I will discuss how to construct a master equation from a collision models discrete-time dynamics. The approach taken generalizes prior methods which take the continuum limit (i.e.
Quantum information science gives us an effective language to describe physical phenomena in terms of the evolution of information. This information paradigm allows us to bring new solutions to old problems, for example to the task of cooling a physical system. While we usually think of cooling as putting a hot system inside a refrigerator, or making contact with a cold bath that cools through random collisions with cold molecules, we can
The University of Waterloo acknowledges that much of our work takes place on the traditional territory of the Neutral, Anishinaabeg and Haudenosaunee peoples. Our main campus is situated on the Haldimand Tract, the land granted to the Six Nations that includes six miles on each side of the Grand River. Our active work toward reconciliation takes place across our campuses through research, learning, teaching, and community building, and is centralized within our Office of Indigenous Relations.
