This event was a continuation of the first ICMS workshop held at ICMS on the same topic, in September 2019, and built upon the existing links between operator algebras, quantum theory and optimisation. The following are sample areas which were covered: 

a) Non-local game theory;
b) Non-commutative combinatorics;
c) Zero-error quantum information theory.

The workshop specifically emphasised the role played in these areas by operator theory and optimisation, and capitalised on the deep connections between operator algebra theory and quantum information theory that have been developed in the past decade.
