Epidemic Learning: Boosting Decentralized Learning with Randomized Communication

Rachid Guerraoui, Anne-Marie Kermarrec, Sadegh Farhadkhani, Rafael Pereira Pires, Rishi Sharma, Marinus Abraham de Vos

We present Epidemic Learning ( EL ), a simple yet powerful decentralized learning (DL) algorithm that leverages changing communication topologies to achieve faster model convergence compared to conventional DL approaches. At each round of EL, each node sen ...

Non-classical photon-phonon correlations at room temperature

Santiago Tarrago Velez

With the development of quantum optics, photon correlations acquired a prominent role as a tool to test our understanding of physics, and played a key role in verifying the validity of quantum mechanics. The spatial and temporal correlations in a light fie ...

Neural Design Space Exploration

Pierre Dillenbourg, Richard Lee Davis, Kevin Gonyop Kim, Wei Jiang

We have developed a new tool that makes it possible for people with zero programming experience to intentionally and meaningfully explore the latent space of a GAN. This tool was developed to provide a means for designers to explore the "design space" of t ...

Crystalline materials for microresonator-based quantum optics

Clément Christian Javerzac-Galy

Hybrid quantum systems are composed of different physical components that can perform simultaneously several tasks such as quantum computing, quantum sensing and quantum communication. Photons are at the core of many of the functionalities of these systems ...

Interplay of S and As in Mekong Delta sediments during redox oscillations

Rizlan Bernier-Latmani, Laurent Louis José Charlet

The cumulative effects of periodic redox cycling on the mobility of As, Fe, and S from alluvial sediment to groundwater were investigated in bioreactor experiments. Two particular sediments from the alluvial floodplain of the Mekong Delta River were invest ...

CubeSat quantum communications mission

Edoardo Charbon

Quantum communication is a prime space technology application and offers near-term possibilities for long-distance quantum key distribution (QKD) and experimental tests of quantum entanglement. However, there exists considerable developmental risks and sub ...

Cavity Quantum Electrodynamics with Site-Controlled Pyramidal Quantum Dots in Photonic Crystal Cavities

Milan Calic

Cavity quantum electrodynamics encompasses the study and control of the interactions between quantum light sources and resonant modes of optical cavities. The subject of this thesis is cavity quantum electrodynamics with semiconductor quantum dots (QDs), w ...

Device-independent state estimation based on Bell's inequalities

Timothy Chi Hin Liew

The only information available about an alleged source of entangled quantum states is the amount S by which the Clauser-Horne-Shimony-Holt inequality is violated: nothing is known about the nature of the system or the measurements that are performed. We di ...

Investigation into the coupling of quantum dots to photonic crystal nanocavities at telecommunication wavelengths

Laurent Balet

Recently, the emission of single photons with emission wavelength in the 1.3 µm telecommunication window was demonstrated for InAs quantum dots. This makes them strong candidates for applications such as quantum cryptography, and in a longer term, quantum ...

Superconducting nanowire photon-number-resolving detector at telecommunication wavelengths

Francis Lévy, Konstantinos Lagoudakis, Francesco Marsili, Alessandro Gaggero

Optical-to-electrical conversion, which is the basis of the operation of optical detectors, can be linear or nonlinear. When high sensitivities are needed, single-photon detectors are used, which operate in a strongly nonlinear mode, their response being i ...

On the Security of HB# against a Man-in-the-Middle Attack

Serge Vaudenay, Khaled Ouafi

At EuroCrypt ’08, Gilbert, Robshaw and Seurin proposed HB# to improve on HB+ in terms of transmission cost and security against man-in-the-middle attacks. Although the security of HB# is formally proven against a certain class of man- in-the-middle adversa ...

Quantum Dot Exciton Dynamics Probed by Photon-Correlation Spectroscopy

Elyahou Kapon, Daniel Oberli, Martin Henrik Baier

The dynamics of charging and recombination of photoexcited, site-controlled semiconductor quantum dots (QDs) are investigated using microphotoluminescence (PL) and photon-correlation spectroscopy combined with rate equation modeling. Several species of neu ...

Le management des communautés virtuelles : organisation des processus sociotechniques, vers un modèle générique

Olivier Glassey

In the last three decades the management of information technologies has become a major issue in most organizations. In this context, virtual communities (VC), as a means to technologically foster collective social exchanges, are often proposed as viable s ...
