Video Library

Since 2002 Perimeter Institute has been recording seminars, conference talks, public outreach events such as talks from top scientists 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 and 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 arXiv.org. 

Accessibly by anyone with internet, Perimeter aims to share the power and wonder of science with this free library.

We show that entanglement harvested from a quantum field
by interaction with local detectors undergoing anti-parallel acceleration can
be used to measure the distance of closest approach between the two detectors.
Information about the separation is stored nonlocally in the phase of the joint
state of the detectors after the interaction; a single detector alone contains
none. We model the detectors as two-level quantum systems accelerating
uniformly  through the Minkowski vacuum

Recently striking connections have been discovered between the research fields of black hole soultions in string theory and the one of entanglement measures in quantum entanglement theory.For the emerging research field the term The Black Hole/Qubit Correspondence has been coined. The basic idea is that wrapping configurations of extended objects in extra dimensions can  give rise to interesting realizations of entangled systems and black holes at the same time. The geometry of the extra dimensions and the wrapping type determines the entangled system in question.

Two different branches of theoretical physics, string theory and quantum information theory (QIT), share many of the same features, allowing knowledge on one side to provide new insights on the other. In particular the matching of the classification of stringy black holes and the classification of four-qubit entanglement provides a falsifiable prediction in the field of QIT.

Space offers a very unique
environment for quantum physics experiments at regimes for distance and
velocity not possible on ground. In the recent years there have been a range of
theoretical and experimental studies towards the feasibility of performing
quantum physics and quantum information science experiments in space.

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.

We
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.
