Whilethe number of qubits, or quantum bits, manipulated by quantum computers has risen in 10 years from a few dozen to a few hundred, major issues such as qubit stability and decoherence effects still limit applications. However, the potential exponential acceleration of calculations, considered revolutionary or devastating (for cryptography, for example), makes it critical for engineers, professionals and companies to increase their skills in this field. Often grouped together under the epithet "Quantum", the related sciences and technologies are both an industrial challenge and a matter of national and European sovereignty. For more than a decade, Télécom Paris has been developing a range of training programs, including the Grande École (engineering) program, master's programs and short continuing education courses (awareness-raising or expertise) and certification programs for professionals.
