Explore a thought-provoking colloquium presentation from the Centre for Quantum Technologies where Alexia Auffèves from Institut Neel - CNRS, Majulab and CQT discusses the critical intersection of quantum technologies and energy consumption. Discover the motivations, ambitions, and methodology behind establishing a transverse quantum energy initiative (QEI) that bridges quantum thermodynamics, quantum information science, quantum physics, and engineering. Learn about the overlooked energetic footprint of quantum technologies despite their promising potential for revolutionizing information processing, and understand why developing energy-efficient, sustainable quantum technologies through QEI is crucial for achieving true quantum advantage in the future.
