Bell's local causality in local classical and quantum theory
with Gabor Hofer-Szabo

Bell's local causality in local classical and quantum theory
Presented by Gabor Hofer-Szabo
Located in LAK 2.06

The aim of the talk is to give a clear-cut definition of Bell’s notion of local causality. Having provided a framework, called local physical theory, which integrates probabilistic and spatiotemporal concepts, we formulate the notion of local causality and relate...

Picturing Quantum Processes
with Bob Coecke

Picturing Quantum Processes
Presented by Bob Coecke
Located in LAK 2.06

We present a purely diagrammatic account on quantum theory.  The conceptual underpinning is to take composition of systems as the primitive connective, having drawn lessons from some of the shortcomings of other axiomatic approaches.  The symbolic underpinning of the approach...

A general perspective on time observables
with Bryan Roberts

A general perspective on time observables
Presented by Bryan Roberts
Located in LAK 2.06

I propose a general geometric framework in which to discuss the existence of time observables. This frameworks allows one to describe a local sense in which time observables always exist, and a global sense in which they can sometimes exist...

Adventures off the mass-shell
with Adam Caulton

Adventures off the mass-shell
Presented by Adam Caulton
Located in LAK 2.06

What is the correct possibility space for a given particle of a quantum field?  The firm orthodoxy, initiated by Wigner in 1939, is that we should look to the irreducible representations of the Poincaré group.  But the justifications for this...

Infinite Quantum-Classical Separations
with Chris Perry

Infinite Quantum-Classical Separations
Presented by Chris Perry
Located in LAK 2.06

How much of an advantage can quantum mechanics give over its classical counterpart? This very much depends on the task and measure under consideration. Take, for example, communication protocols where two players are given inputs x and y respectively and...

Generalised probabilistic theories meet Bayesian networks
with Raymond Lal

Generalised probabilistic theories meet Bayesian networks
Presented by Raymond Lal
Located in LAK 2.06

Bayesian networks provide a powerful tool for reasoning about probabilistic causation, used in many areas of science.  They are, however, intrinsically classical.  In particular, Bayesian networks naturally yield the Bell inequalities.  Inspired by this connection, we generalise the formalism of...

Take quantum foundations, add even more noise, and you get applications!
with Sania Jevtic

Take quantum foundations, add even more noise, and you get applications!
Presented by Sania Jevtic
Located in LAK 2.06

The superiority of quantum computers over classical ones disappears when the quantum system is subjected to noise. At sufficiently high noise levels, the classical computer can efficiently simulate the noisy quantum statistics. One way of defining this noise threshold is...
