Video Library

Since 2002 Perimeter Institute has been recording seminars, conference talks, and public outreach events using video cameras installed in our lecture theatres.  Perimeter now has 7 formal presentation spaces for its many scientific conferences, seminars, workshops and educational outreach activities, all with advanced audio-visual technical capabilities.  Recordings of events in these areas are all available On-Demand from this Video Library and on Perimeter Institute Recorded Seminar Archive (PIRSA)PIRSA is a permanent, free, searchable, and citable archive of recorded seminars from relevant bodies in physics. This resource has been partially modelled after Cornell University's

We will explore different results on  relativistic quantum information and general relativistic quantum optics whose aim is to provide scenarios where relativistic quantum effects can be experimentally accessible. Traditionally, relativistic quantum information has been far away from the experimental test, but the discipline is close to the transition point where experimental outcomes will soon arise.

investigate entanglement creation between modes of a quantum field contained
within a cavity which undergoes noninertial motion. We find that, in the the low acceleration regime, or equivalently in the small
cavity regime, entanglement can be created from initially separable states and
it can be linearly increased by repeating travel scenarios. We are able to fin analytically how all the parameter involved affect the
entanglement. We suggest that this can be of interest when looking for

Thought experiments involving quantum mechanics in the presence of closed time-like curves (CTCs) seem to have little to do with reality. However, even particles that traverse the CTC passively and without interactions can lead to highly non-trivial effects, such as the maximal violation of the uncertainty principle. Moreover, these effects may carry over to curved space-times without CTCs, presenting novel opportunities for testing non-standard physics in the relativistic regime.

I will discuss a new proposal with the potential to experimentally probe the validity of Rindler quantisation from the recent completely localized framework of non-inertial projective detectors of quantum fields.

We introduce a novel approach to measurements in QFT in non-inertial frames. A simple, localised, analytical model of state detection allows us to study all the standard questions of RQI and yielding simple answers with a clear physical interpretation. We apply the model to investigate extraction of the entanglement from the vacuum, completely characterize entangled state of two localised inertial wave-packets in the accelerating frame and study the entanglement degradation as a function of the proper acceleration of the detector.

tests of general relativity performed so far involve systems that can be
effectively described by classical physics. On the other hand, observed gravity
effects on quantum systems do not go beyond the Newtonian limit of the theory.
In light of the conceptual differences between general relativity and quantum
mechanics, as well as those of finding a unified theoretical framework for the
two theories, it is of particular interest to look for feasible experiments
that can only be explained if both theories apply.

While entanglement is believed to underlie the power of
quantum computation

and communication, it is not generally well understood
for multipartite

systems. Recently, it has been appreciated that there
exists proper

no-signaling probability distributions derivable from
operators that do not

represent valid quantum states.  Such systems exhibit supra-correlations

that are stronger than allowed by quantum mechanics, but
less than the
