Public lecture by Bill Unruh, The University of British Columbia

On February 11, 2016 it was announced that gravitational  waves have been detected affecting an instrument on earth. In addition to the realization of a 100 year old prediction the astounding sensitivity of the detector demanded the approaching and overcoming of seemingly fundamental quantum limits on measuring the motion of 25Kg masses. Quantum mechanics is usually thought of applying only to the very small (zeptogrammes and nanometers).

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.

On the geometry of entanglement

Rotem Liss, Technion – Israel Institute of Technology

Entanglement is an important concept in quantum information and computing. In this talk, I present a simple geometrical analysis of all rank-2 quantum mixed states. The analysis is complete for all the bipartite states, and is partial for all the multipartite states.

The Quantum Neutron

Dmitry Pushin

The neutron, one of the most common building blocks of matter, is also a unique probe for studying materials and fundamental interactions. The only electrically-neutral nucleus, the neutron passes through most materials with ease, even at the lowest energies. Nowadays neutrons, even with their ~ 15 minute lifetime, are used to study problems ranging from charging and discharging of common batteries to cosmological dark energy. Here I will focus on the neutron as a quantum particle.

Chiral Atomically Thin Films

Cheol-Joo Kim, Cornell University

Chiral materials possess left- and right-handed counterparts linked by mirror symmetry. These materials are useful for advanced applications in polarization optics[1,2], stereochemistry[3,4] and spintronics[5]. In particular, the realization of spatially uniform chiral films with atomic-scale control of their handedness could provide a powerful means for developing nanodevices with novel chiral properties.
