Witnesses of non-classicality beyond quantum theory

The theory of quantum computation has brought us rapid technological developments, together with remarkable improvements in how we understand quantum theory. In this talk, I shall describe the foundations of a theoretical programme to extend the quantum theory of computation beyond quantum theory itself, based on the recently proposed constructor theory. I will then explain a recent application of this new approach to the problem of witnessing quantum effects in gravity.

Note, Chiara is joining us online for the colloquium. We will live stream from the Higgs Centre though and coffee and light refreshments will be provided in the room.
