Some logical aspects of contextuality
In this talk I will review the basic aspects of contextuality and explain the connection to graph theory and magic state distillation following the paper "Contextuality Supplies the Magic to Quantum Computation". I will then discuss a logical version of contextuality.
If time permits, I will explain some work in progress in defining a logical criterion for identifying states useful for magic state distillation.
The main references for the talk are:

This is work in progress with Cihan Okay, Yash Totani and Amolak Kalra.
