PIRSA:11070057  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Quantum Vacuum Polarization Effects and the Estimation of the Stabel Vacuum Lifetime in the Field of a Superheavy Necleus
Speaker(s): Aleksandra Petrova
Abstract: The vacuum polarization effects in superstrong Coulomb and laser fields are considered from the point of view of the generalized quantum dynamics formalism. The vacuum decay time in superstrong electromagnetic field is discussed.

PIRSA:11070059  ( MP4 Medium Res , MP3 , PDF ) Which Format?
What's the Entropy of Gravity?
Speaker(s): Francesca Vidotto
Abstract: I present a proposal, originally motivated by a result in graph theory: the entropy function of a density matrix naturally associated to a simple undirected graph, is maximized, among all graphs with a fixed number of links and nodes, by regular graphs.I recover this result starting from the Hamilto... read more

PIRSA:11070060  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Creating Spacetime
Speaker(s): Fotini Markopoulou
Abstract: Our understanding of the physical world at the most fundamental level is based on two theories: quantum theory and general relativity. They are impressively successful but only when each is considered on its own. In situations where both play a role, we are reduced to puzzles and absurdity. Hence th... read more

PIRSA:11070091  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Introduction to Quantum Information Processing
Speaker(s): Michele Mosca
Abstract: Information processing is a physical process, and thus the powers and limitations of an information processing device depend on the laws of physics. The “classical” framework for physics has long been replaced by quantum physics. Over the past century we have moved from observing quantum phenome... read more

PIRSA:11070062  ( MP4 Medium Res , MP3 , PDF ) Which Format?
A Brief Introduction to Quantum Cryptography
Speaker(s): Stacey Jeffery
Abstract: By exploiting the properties of quantum mechanical systems, two parties can achieve cryptographically secure communication in a manner not possible in a purely classical world, through the process of quantum key distribution. In this talk, I will briefly introduce the field of cryptography and expla... read more

PIRSA:11070063  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Super-polynomial Speed-up for a Quantum Computer on Boolean Trees
Speaker(s): Shelby Kimmel
Abstract: We can prove that for certain problems, quantum computers do better than classical computers. I will introduce the query complexity framework, which lets us compare classical and quantum computers, and then describe a problem where quantum computers do better than classical. The problem I will discu... read more

PIRSA:11070064  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Thermodynamics and Information
Speaker(s): Lidia del Rio
Abstract: Thermodynamics is, at heart, a probabilistic theory about the state of physical systems. Traditionally, however, our knowledge of systems is modelled implicitly: for instance, it is often assumed that we only have access to a few macroscopic parameters, like the temperature, energy, or volume of a g... read more

PIRSA:11070065  ( MP4 Medium Res , MP3 , PDF ) Which Format?
On the Existence of a Residue Entangled State in eLOCC Transformations
Speaker(s): Monika Deviat
Abstract: Quantum entanglement is a valuable resource in the field of quantum information science and allows one to accomplish many information processing tasks. In quantum transformations an entangled state A can be converted to another state B through local operations assisted by classical communication (LO... read more

Mathematics and Topological Quantum Computation
Speaker(s): Lucy Liuxuan Zhang
Abstract: TBA

PIRSA:11070067  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Introduction to Spin Qubits in Lateral Quantum Dots
Speaker(s): Chloe Bureau-Oxton
Abstract: A quantum computer is a computer fabricated using quantum bits (qubits) that uses the quantum properties of matter (entanglement, superposition of states, etc.). Such a computer would allow certain calculations to be done exponentially more quickly than with a classical computer. An electron in a qu... read more
