Quantum state and channel discrimination, and conditions for channel reversibility
The discrimination of quantum states and channels is fundamental in quantum information theory. For the abstract problem of quantum channel discrimination, I will discuss the role of the ancilla dimension in achieving optimal discrimination, relative to the input and output dimensions of the channels. In particular, I will present a family of channels containing arbitrary finite gap between the input and output dimensions, yet still requiring an ancilla as large as the input for optimal discrimination, and will discuss follow up questions.

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 co-ordinated within the Office of Indigenous Relations.
