Title: Fixed-size schemes for certification of large quantum systems

Speaker: Laura Mancinska
Affiliation: QMATH, University of Copenhagen
Location: MC 5501 or please contact Emma Watson for Zoom link


In this talk I will introduce the concept of self-testing which aims to answer the fundamental question of how do we certify proper functioning of black-box quantum devices. We will see that there is a close link between self-testing and representations of algebraic relations. We will leverage this link to propose a family of protocols capable of certifying quantum states and measurements of arbitrarily large dimension with just four binary-outcome measurements.

This is a joint work with Chris Schafhauser and Jitendra Prakash.
