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.

Abstract: Strongly-driven nonlinear optical processes such as spontaneous parametric down-conversion and spontaneous four-wave mixing can produce multiphoton nonclassical beams of light which have applications in quantum information processing and sensing. In contrast to the low-gain regime, new physical effects arise in a high-gain regime due to the interactions between the nonclassical light and the strong pump driving the nonlinear process. Here, we describe and experimentally observe a gain-dependent group delay between the multiphoton pulses generated in a high-gain type-II spontaneous parametric down-conversion source. Since the group delay introduces distinguishability between the generated photons, it will be important to compensate for it when designing quantum interference devices in which strong optical nonlinearities are required.

Integrating electric vehicles (EV) and distributed energy resources (DER) presents multiple challenges while offering solutions for grid operation. Using internet-of-things (IoT) technology for EVs and DERs improves the resiliency of the grid but introduces cyber vulnerabilities. Minimizing the impact of cyber attacks on the grid depends on factors such as cyber defense planning, grid operator training and using metrics for operational decision-making. A standardized metric system is required to quantify cyber resiliency and use them for systems with edge devices. The talk covers the basics of cyber-power security and resiliency, operational decision tools, resiliency metrics for the grid and a testbed to validate these cyber resilience tools.
