World Quantum Day

Quantum mechanics began in 1900 with the introduction of the particle properties of electromagnetic radiation by the German scientist Max Planck. In 1924, Louis Dubroy stated that there is symmetry in nature and that if radiation can behave as both a particle and a wave, then matter must also have wave properties. Diffraction of particles, uncertainty principle, quantum tunneling, discretization of energy levels and some other phenomena of quantum mechanics are the direct result of wave property of particles. In this introductory presentation, some basic concepts related to quantum mechanics will be briefly explained in comparison with the wave properties of electromagnetic radiation. In this presentation, milestones in the evolution and development of quantum computing and quantum communication technologies are introduced, from the origin of the idea to laboratory implementation, field tests, and practical use.
