Overview The field of Artificial Intelligence is taking the industry (and the world) by storm. The launch of ChatGPT started a mass adoption phenomenon, which is now followed by an avalanche of new products and solutions addressing every possible problem space. Malicious hackers have also put AI to good use, but so did the White Hat hackers, such as Frédéric and his team. This talk will level-set the understanding about Large Language Models (LLM) and Generative AI for computer scientists and software developers who might not be intimately familiar with the field. Frédéric will then take us further into some of the applications in cybersecurity. Abstract Large Language Models and Generative AI have completely reshaped the landscape of Artificial Intelligence the last two years. Progresses have been made on architectures, training methods, and the community has shared large datasets along with pre-trained models, allowing for new usages at a relatively low cost. In the cybersecurity defender's path, new malicious tools drove efforts on innovative methods to improve their detection. We propose a modern and effective method of detecting file maliciousness, by using an LLM initially trained on computer code. The focus will be on the process we set up and the decision we made to solve this problem, with an emphasize of the generalization of our approach. We will explain how LLM can help solve a large panel of problems related to texts. In addition, we will explain the outcomes of this work : in particular, we will explain how we were able to use the trained model and ask it "where it was wrong", shedding lights on errors in the training datasets. We will explain where these errors came from, and how we were able to improve the model iteratively by correcting them, allowing more people to reproduce our findings and fixing pitfalls coming with noisy datasets. Working in a field where sometimes the line is thin between an "administrator" and a "threat actor", we will also open the discussion on how you can define maliciousness depending on your objectives. Key takeaways : -What is an LLM and what it is not? -How much does it cost to use one for our own purpose? -What are the key steps of a training process? -An intro to cybersecurity : what are we trying to detect? -How did we build our datasets? -The results -What can the data engineer and the cybersecurity analyst learn from these results?

[]Silicon Valley is commonly acknowledged as the tech capital of the world. How did Silicon Valley come into being, and what can we learn? The story goes back to local Hams trying to break RCA's tube patents, Stanford "angel" investors, the sinking of the Titanic, WW II and radar, and the SF Bay Area infrastructure that developed – these factors pretty much determined that the semiconductor and IC industries would be located in the Santa Clara Valley, and that the Valley would remain the world’s innovation center as new technologies emerge, and be the model for innovation worldwide. This talk will give an exciting and colorful history of development and innovation that began in Palo Alto in 1909. You'll meet some of the colorful characters – Cyril Elwell, Lee De Forest, Bill Eitel, Charles Litton, Fred Terman, David Packard, Bill Hewlett, Bill Shockley and others – who came to define our worldwide electronics industries through their inventions and process development. You'll understand some of the novel management approaches that have become the hallmarks of its tech startups. Many of these attributes can be found in other technology hubs; however, the SF Bay Area has five generations of experience, as well as a "critical mass" of talent, making it difficult for others to catch up. In this talk, the key attributes will be illustrated and analyzed, for consideration by other tech hubs, and for entrepreneurs interested in creating their own start-ups or understanding them. Speaker(s): Paul Wesling, Agenda: The event will start at 11:30AM with a short networking interaction. The talk will then begin at 12:00PM and conclude around 1-1:15PM, with questions for the last 10-15 minutes of the talk. Food and drink will be provided.

Abstract: Photonic integration has been at the center of photonic activity for several years. Over this period, great strides have been made to increase the integration density and integrated chip functionality. This talk will work its way up from the drivers for photonic integration – why do we need Photonic Integrated Circuits (PICs)? What are their similarities and differences with Electronic Integrated Circuits (EICs)? This analysis of integration drivers will lead to a discussion of recent progress on the main paths: monolithic, heterogeneous and hybrid. The talk will conclude with possible approaches to meet the additional demanding considerations for future Quantum PICs. Co-sponsored by: Co-sponsored by National Research Council, Canada. Optonique.

Abstract: Exploiting spatial correlations between photons is a fundamental in quantum imaging. Correlation-based imaging, a scheme whereby one photon from a pair interacts with an object before reaching the detection system. The joint measurement of the two photons then reveals the image of the object. Though the image reconstruction was initially implemented using computational techniques that employ a single pixel with no spatial resolution on its own, modern implementations can make use of arrays of single-photon sensitive detectors. Novel imaging sensors such as arrays of single photon avalanche diodes (SPADs) have enabled two- and three-dimensional imaging, the latter being enabled by the high temporal resolution. Furthermore, their high-frame rate, compared to rival technology, dramatically reduces the acquisition time required to spatially characterise quantum states and form a correlation image. In this talk, we will provide an overview of the recent developments in 2D, and 3D correlation-based imaging using photon pairs and enabled by SPAD cameras. Particularly, we will focus on optical designs geared towards applications in microscopy.

Spin Polarized Transport in Monolayer WSe2 Quantum Structures Abstract: Monolayer transition metal dichalcogenides (TMDs), a semiconducting member of the two-dimensional material family, have been suggested to be promising candidates for various quantum applications. However, challenges associated with the quality of electrical contacts in TMDs have hampered the progress of transport studies, especially at low temperature and in the low carrier density regime. In this talk, a device structure is presented which allows us to obtain low resistance ohmic contacts to monolayer TMDs while still accessing the low carrier density regime in transport experiments. The low-temperature magneto-transport measurements resulting from this fabricated device is presented and the unexpected spin polarized states are discussed. ------------------------------------------------------------------------ Transport polarisé de spin dans les structures quantiques monocouches WSe2 Résumé : Il a été suggéré que les dichalcogénures de métaux de transition (TMD) monocouches, un membre semi-conducteur de la famille des matériaux bidimensionnels, seraient des candidats prometteurs pour diverses applications quantiques. Cependant, les défis associés à la qualité des contacts électriques dans les TMD ont entravé la progression des études de transport, en particulier à basse température et dans le régime de faible densité de porteurs. Dans cet exposé, une structure de dispositif est présentée qui nous permet d'obtenir des contacts ohmiques à faible résistance avec des TMD monocouches tout en accédant au régime de faible densité de porteurs dans les expériences de transport. Les mesures de magnéto-transport à basse température résultant de ce dispositif fabriqué sont présentées et les états polarisés en spin inattendus sont discutés.

A Strategic Si3N4 materials platform for Integrated Quantum and Nano Technologies (Made in Canada!) Abstract: Silicon nitride has recently gained a lot of interest within the photonic device community, because of its unique properties, as an attractive materials platform of choice for a wide range of applications including sensing, metrology, nonlinear optics, quantum information processing and telecommunications. We report on an optimization procedure for depositing low-loss silicon nitride films at temperatures of 760˚C and 820˚C using low-pressure chemical vapor deposition. They were characterized in terms of quality and compositional proximity to stoichiometric silicon nitride. Films deposited at 760˚C showed a higher stoichiometry, with a silicon-to-nitrogen ratio of 0.744, when compared to the 820˚C film, which had a ratio of 0.77. We found the film deposited at the lower temperature had a smoother surface and exhibited lower optical losses. We investigated the impact of film stress on the refractive index of the film and found that removing the backside nitride from the wafer after deposition has a major effect on refractive index values. When using these films for integrated nonlinear and quantum applications, such as frequency conversion or soliton generation, knowledge of how the index changes with wafer and fabrication processing is critical for predicting the correct geometries, and the concomitant group velocities, needed to realize such quantum technologies. The measured losses from fabricated devices showed that our nitride material is comparable to the leading foundries if not better than them regarding the film quality and losses. ------------------------------------------------------------------------ Une plateforme stratégique de matériaux Si3N4 pour les technologies quantiques et nano intégrées (fabriquée au Canada !) Résumé : Le nitrure de silicium a récemment suscité beaucoup d'intérêt au sein de la communauté des dispositifs photoniques, en raison de ses propriétés uniques, en tant que plate-forme matérielle attrayante de choix pour un large éventail d'applications, notamment la détection, la métrologie, l'optique non linéaire, le traitement de l'information quantique et les télécommunications. Nous rapportons une procédure d'optimisation pour le dépôt de films de nitrure de silicium à faibles pertes à des températures de 760 °C et 820 °C par dépôt chimique en phase vapeur à basse pression. Ils ont été caractérisés en termes de qualité et de proximité de composition avec le nitrure de silicium stœchiométrique. Les films déposés à 760 °C présentaient une stœchiométrie plus élevée, avec un rapport silicium/azote de 0,744, par rapport au film à 820 °C, qui présentait un rapport de 0,77. Nous avons constaté que le film déposé à la température la plus basse avait une surface plus lisse et présentait des pertes optiques plus faibles. Nous avons étudié l'impact de la contrainte du film sur l'indice de réfraction du film et avons constaté que le retrait du nitrure arrière de la tranche après le dépôt avait un effet majeur sur les valeurs de l'indice de réfraction. Lors de l'utilisation de ces films pour des applications non linéaires et quantiques intégrées, telles que la conversion de fréquence ou la génération de solitons, la connaissance de la façon dont l'indice change avec le traitement de la plaquette et de la fabrication est essentielle pour prédire les géométries correctes et les vitesses de groupe concomitantes, nécessaires à la réalisation de telles technologies quantiques. Les pertes mesurées des appareils fabriqués ont montré que notre matériau nitrure est comparable aux principales fonderies, voire meilleur, en termes de qualité du film et de pertes.
