About :

By Jean Dalibard, holder of the Atoms and Radiation chair at the Collège de France. In 1924, Louis de Broglie hypothesized that each particle of matter has a wave nature. Einstein was enthusiastic and de Broglie won the Nobel Prize in 1929. This discovery now has concrete applications, from electronic components to the future "quantum computer". In 1924, in his doctoral thesis, Louis de Broglie hypothesized that a wave could be associated with each material particle. Upon learning of this, an enthusiastic Einstein declared that de Broglie had "lifted a corner of the great veil". Five years later, it earned its author the Nobel Prize in Physics "for his discovery of the wave nature of electrons". Louis de Broglie's conceptual breakthrough played a fundamental role in the development of quantum physics, which now governs our understanding of the microscopic world and is the basis for countless applications, from the electronic components we use every day to a hypothetical "quantum computer".
