PIMS-CRG Seminar / UCM Applied Math Colloquium: Daniel Appelö
Topic
Kraus Is King: High-Order Completely Positive and Trace Preserving (CPTP) Low Rank Method for Open Quantum Computing Systems
Speakers
Details
In this talk, we will:
1. Introduce the most basic concepts in quantum computing.
2. Briefly highlight examples of quantum algorithms where the skills of a numerical analyst can be of use.
3. Describe one type of quantum computing hardware (a transmon) and how it is modeled.
4. Show how to design high order accurate methods that exploit low rank structure in the density matrix while respecting the essential structure of the Lindblad equation. Our methods preserve complete positivity and are trace preserving.
