The number theory of quantum information

Jon Yard, IQC

Abstract: Quantum-mechanical amplitudes and unitaries are typically expressed over the complex numbers. Because there is a continuum of complex numbers, classical computations of quantum systems generally utilize finite-precision approximations by rational numbers.

Oral defence Monday, June 4, 1:30 p.m., RAC 2009.

On Thursday, June 7 the Institute for Quantum Computing (IQC) and the Perimeter Institute for Theoretical Physics (PI) will participate in the one-day Many-body States and Dynamics Workshop.

The goal of the workshop is to  describe ongoing efforts to experimentally realize quantum many-body states and dynamics, and discuss interesting classes of states and dynamics that could be targeted.

Speaker: Tom Hunter and Neil Henderson

Abstract: A lot of different concepts and possibilities have been discussed. The final session will recap those and put them in perspective, with emphasis on the relevance to a "typical" university start up and the people involved.

Quantum secret sharing (QSS) mainly deals with the splitting and distributing of an arbitrary secret among n sharers using quantum resources. While quantum secret sharing schemes often use shared entangled states, it is also possible to define a notion of quantum secret sharing without the use of entangled states.

Surface Acoustic Waves in Quantum Systems

Mats Powlowski

​Surface acoustic waves (SAWs) are acoustic phonons that travel along the surface of a material and have been used for a wide variety of purposes, from RF filters to acoustic cavities to biosensors.

A nonlocal game with a synchronous correlation is the ideal protocol for quantum key distribution. In this work we examine analogues of Bell's inequalities for synchronous correlations. We show that unlike in the nonsynchronous case (e.g. with the CHSH inequality) there can be no quantum Bell violation among synchronous correlations with two measurement settings. However we exhibit explicit analogues of Bell's inequalities for synchronous correlation with three measurement settings and two outputs that do admit quantum violations.

This two-day workshop is an opportunity for the people working in the field to discuss and compare different approaches, our ability to reduce assumptions and together attempt to define a coherent view on security proofs, claims and assumptions in practical QKD.
