Simon Phoenix: Quantum Keys - Are They Just a Flash in the Security Pan

Simon Phoenix, Khalifa University

Abstract

The birth of quantum key distribution (QKD) 2 decades ago was accompanied by headlines the world over that the age of perfect security had finally dawned. The media, not noted for its restraint, can be forgiven. But so, too, can the physicists who, by and large, spawned such claims. In the cut-throat world of research funding, quantum key distribution was a godsend. I played the game too.

Chris Sutherland: Mode Mismatch in a Mutually Unbiased Basis Measurement Scheme

Chris Sutherland, Institute for Quantum Computing (IQC)

Abstract

Quantum cryptography protocols for qudit systems have been well established, but the ways to implement a mutually unbiased basis measurement have not been. In this talk I will describe the proposed measurement scheme, and also describe how to account for the common experimental challenge of mode-mismatch between two distinct laser pulses. I will also show how this effects the result of the measurement, and how much mode mismatch can be tolerated.

Francesco Buscemi (Nagoya University): Q+ Hangout

Francesco Buscemi (Nagoya University), Institute for Quantum Computing (IQC)

Abstract

Title: - All entangled quantum states are nonlocal: equivalence between locality and separability in quantum theory

In this talk I will show how, by slightly modifying the rules of
nonlocal games, one can prove that all entangled states violate local
realism.
