Single Photon Source on a Breadboard
Erwann Bocquillon - Institute for Quantum Computing (IQC)
In quantum information, one can prove that a secure quantum cryptography channel based on photon key distribution requires reliable single photon sources. If not, a potential eavesdropper may be able to get information using the extra photons. Current sources are based on either attenuated laser… -
Subsystem Quantum Error Correcting Codes
Andrea Casaccino - University of Siena
The essential insight of quantum error correction was that quantum information can be protected by suitably encoding this quantum information across multiple independently erred quantum systems. Recently it was realized that, since the most general method for encoding quantum information is to… -
Degradability of Bosonic Gaussian Channels
Filippo Caruso - Scuola Normale Superiore di Pisa
The notion of weak-degradability of quantum channels is introduced by generalizing the degradability definition given by Devetak and Shor. Exploiting the unitary equivalence with beam-splitter/amplifier channels we then prove that a large class of one-mode Bosonic Gaussian channels are either weakly… -
A New Protocol for Loss-Tolerant Quantum Coin Tossing
Quantum coin tossing is a cryptographic task in which two parties, Alice and Bob, wish to generate a shared random bit but do not necessarily trust each other. This task is completely impossible to realize with classical asynchronous communication but becomes at least partially feasible when quantum… -
Cluster State Quatum Computing in Optical Fibres
Yasaman Soudagar - Polytechnique Montreal
In this presentation I will briefly explain the cluster state model of quantum computing. Then will talk about a scheme that uses polarization and time-bin degrees of freedom of photons in optical fibres for the optical realization of this model. We are currently working on the implementation of… -
An Introduction to One-Way Patterns
The one-way measurement model is a model of quantum computation which is intriguing for its' potential as a means of implementing quantum computers, but also for theoretical purposes for the different way in which it allows quantum operations to be described. Instead of a sequence of unitary gates… -
Quantum Mechanics in Phase Space
Many authors have proposed what are known as "phase-space" or "classical" representations of quantum mechanics. A unifying framework is given which illustrates the relationship among these various theories. Examples relevant to quantum computing will be given. -

Distributed phase reference schemes for QKD: Explicit attacks and security considerations
Cyril Branciard - Université de Genève
"Distributed phase reference schemes are a new class of protocols for Quantum Key Distribution, in which the quantum signals have overall phase-relationships to each other. This is expected to protect against some loss-related attacks. However, proving the full security of these schemes is a new… -
Towards the Production of Entangled Photon Pairs in Optical Fiber via Four-Wave Mixing
Joshua Slater - University of Calgary
Previous experiments on the production of entangled photon pairs directly in optical fiber via four-wave mixing (FWM) have used a single pump laser and produced signal and idler photons with similar wavelengths. We will present the first results of our investigation into the production of widely…
