Quantum Technologies need a Quantum Energy Initiative.*

Quantum technologies are currently the object of high expectations from governments and private companies, as they hold the promise to shape safer and faster ways to exchange and treat information. However, despite its major potential impact for industry and society, the question of their energetic footprint has remained in a blind spot of current deployment strategies. In this talk, I argue that quantum technologies must urgently plan for the creation of a transverse and interdisciplinary quantum energy sector, connecting quantum thermodynamicians, computer scientists and engineers. Structuring this sector is the only path towards sustainable quantum technologies, help reducing the cost of classical information processing, and possibly bring out an energetic quantum advantage.
