QUIDS: A Large-Scale Distributed Framework for Quantum Irregular Dynamics Simulations

Joseph Touzet, Oguz Kaya, Pablo Arrighi, Amélia Durbec

In traditional quantum computing, e.g. in the quantum circuit model, the size of the data structure describing basis elements is well known, because the dimensionality is fixed. General quantum systems, however, exhibit basis elements of variable size, and state spaces having dynamically unbounded...

Multimode coupling and nonlinear dynamics in coupled double-drum resonators

X Zhou, L Flis, T Farah, E Collin, B Djafari-Rouhani, Y Pennec

Parametrically coupled micro- and nano-electromechanical resonators serve as ideal model systems for the study of coherent multimode energy transfer and conversion, offering diverse interaction mechanisms and flexible control of mode coupling [1-3]. In this work, we present experimental and...

Performance of Long Range-Frequency Hopping Spread Spectrum (LR-FHSS) For LoRaWAN Satellite Communication

Puput Adi, Kevin Stekelorom

Some factors that need to be developed in the LoRaWAN satellite communication system are using LR-FHSS (Long Range-Frequency Hoppong Spread Spectrum) to increase resistance to frequency interference and jamming, with the technique of using a small bandwidth per channel and operating on the same...

Noise sources, data process and uncertainties in terahertz time domain spectroscopy

Jeyan Bichon, Noureddin Osseiran, Jean-Francois Lampin, Romain Peretti

The first terahertz time domain spectroscopy (THz-TDS) experiments are now well-established, and fully autonomous systems have been commercially available for over a decade. This has led to the increasing adoption of THz-TDS by research groups outside the core THz community, as well as by...

Chalcogenide nano-optomechanical phase change metasurface

Ding Li, Abbas Sheikh Ansari, Avik Mandal, Behrad Gholipour, Xin Zhou, Jun-Yu Ou

Tuning any mechanical resonator like a guitar string requires continuous force and energy. Phase change chalcogenide semiconductors can provide non-volatile switching of mechanical and optical properties with phase transition. Here, we demonstrate a new class of reconfigurable nano-optomechanical...

Light security scheme for Cooperative, Connected and Automated Mobility (CCAM)

Ramzi Boutahala, Hacène Fouchal, Marwane Ayaida

Cooperative, Connected and Automated Mobility (CCAM) is a new paradigm adopted by academia and industry in order to provide safe, secure and sustainable mobility on all kinds of roads (highways, urban and rural roads). CCAM takes advantage of Cooperative Intelligent Transport Systems (C-ITS) to...

Infrastructure intelligente pour l'allocation de puissance dans les systèmes MIMO de type cell-free

Philippe Mathieu, Antoine Nongaillard, Eric Pierre Simon

Les réseaux de télécommunication actuels, basés sur des stations centralisées, ne répondent pas aux besoins croissants en bande passante et aux nouveaux usages comme l'IoT ou les véhicules connectés. Le paradigme "cell-free" émerge comme une solution, distribuant des points d'..., Current telecommunication networks, based on centralized base stations, do not meet the growing demand for bandwidth and new uses such as IoT or connected vehicles. The "cell-free" paradigm emerges as a solution, distributing less powerful but more numerous access points over a wide area...

Physical and electrical characterizations of low n-doped MOCVD GaN-on-sapphire layers for power electronics applications

Ndembi Ignoumba-Ignoumba, Camille Sonneville, Adrien Bidaud, Pierre Brosselard, Eric Frayssinet, Florian Bartoli, Yvon Cordier, Farid Medjdoub, Dominique Planson, Cyril Buttay

This work presents physical and electrical characterizations of low n-doped MOCVD GaN-on-sapphire layers and associated quasi-vertical Schottky Barrier Diodes (SBDs). Samples GaN drift layers have globally a similar quality as examined by XRD, AFM Raman spectroscopy, C-V measurements and I-V...
