PhD Seminar • Quantum Computing / Quantum Information — Self-embezzlement using C*-dynamicsExport this event to calendar

Wednesday, December 5, 2018 — 2:00 PM EST

Li Liu, PhD candidate
David R. Cheriton School of Computer Science

Following my previous seminar talk on embezzlement of entanglement, this talk introduces a more general version of the problem — self-embezzlement. Instead of embezzling a pair of entangled state from a catalyst, self-embezzlement aims to create two copies of the catalyst state using only local operators. 

To achieve this, we introduces a new model describing locality in quantum information, the C*-circuit model. The C*-circuit model is a special case of the commuting operator framework, and uses C*-algebra to describe local quantum systems. One interesting aspect of self-embezzlement is that it cannot be achieved approximately to arbitrary precision in the tensor product framework, thus giving us an example of constant-gap difference between the tensor product and commuting operator framework.
