Overview on FD-SOI candidate for Quantum & Cryogenic design - "Keep cool on these hot topics"
The main objective of this talk is to provide an overview on quantum applications with their technologies and cryogenic temperature design where FD-SOI technology is a natural candidate due to its proven functionalities. Thus, a brief introduction to classical, neurological and quantum computing is described to provide a general framework for this main presentation. Next, quantum technologies are listed here with a particular emphasis on spin qubits, particularly with the silicon substrate. The exceptional performances of CMOS FD-SOI technology are discussed through measurements and simulations on: elementary spin qubit, stand-alone MOS transistor @ cryo with front and back gate control at cryogenic temperature. In addition, BICMOS and Photonics technologies are also possible technologies to solve specific points. This overview makes it possible to give a projection on possible architectures with their expectations. Thus, key parameters of a system raise the question of noise, aging, power, reliability and severe environmental constraints. These new quantum design challenges will lead to innovative solutions and applications in the near future and will enrich cryogenic electronic designs for other applications, namely: space, fundamental physics and astrophysics detectors, medicine, energy optimization, data encryption, AI etc.

Moore’s Law and planetary boundaries – How to conduct ICT research in the Anthropocene?
Six of the nine planetary boundaries are transgressed, which have led Humanity in the Anthropocene, i.e. out of the safe operating space, where we clearly see the effects of climate change, biodiversity loss and pollution. Information and Communication Technologies (ICTs) contribute to the exceedance of these boundaries e.g. by directly contributing to 2-4% of the global greenhouse gas emissions. Research in ICT mostly follows the mainstream agenda of improving the technological efficiency with respect to energy and resource consumption. This is best illustrated by Moore’s Law but all research in energy-efficient computation and communications also fall in this category. However, this quest for efficiency so far have failed to reduce the absolute environmental footprint of ICTs. In this talk, we will try to decode the socio-economic conditions that prevented us to turn the efficiency improvement into footprint reduction with a focus on semiconductor manufacturing, given the current drive from the European Chips Act. We will then try to shape a necessary socio-ecological transition to include sobriety in ICT research and innovation while rethinking our socio-economic models.
