Quantum information in tensor networks

Michael Walter, Stanford University

In this talk, we explore how quantum information is encoded in tensor networks. To this end, we study the properties of random tensor networks with large bond dimension. We find that, from the perspective of quantum information theory, entanglement emerges from the geometry of the network by a multipartite entanglement distillation process.

Extended nonlocal games and monogamy-of-entanglement games

Vincent Russo, Institute for Quantum Computing

Two-player one-round games have served to be an instrumental model in theoretical computer science. Likewise, nonlocal games consider this model when the players have access to an entangled quantum state. In this talk, I will consider a broader class of nonlocal games (extended-nonlocal games), where the referee shares an entangled state along with the players.

Towards Integrated Photonics for Quantum Computation

Hugo Cable, University of Bristol, UK

I will give an overview of work at the Centre for Quantum Photonics towards implementation of large-scale linear-optical quantum computing (LOQC) using quantum photonics. Our current research addresses the key obstacles to scalable LOQC, namely overcoming nondeterminism, achieving loss tolerance, and manufacturability.
