For an “imaginary” number, 𝑖 is surprisingly handy across many scientific disciplines: It shows up in geometry, optics, signal analysis, and, controversially, in quantum mechanics.

Physicists Take the Imaginary Numbers Out of Quantum Mechanics | Quanta Magazine
Quantum mechanics has at last been formulated exclusively with real numbers, bringing a mathematical puzzle at the heart of the theory into a new era of inquiry.

Les sciences et technologies quantiques reposent sur la capacité de contrôler individuellement des objets quantiques. Nées de la rencontre entre physique, informatique et mathématiques, elles s’appuient sur des concepts fascinants comme la superposition et l’intrication pour ouvrir des perspectives inédites : calculs ultra-puissants, capteurs d’une précision extrême et communications inviolables. À UPCité, recherche, formation et innovation s’unissent pour accélérer la transition vers une nouvelle ère scientifique et technologique.
