Quantum: Advancing Photonics for 100 Years  

出　　处：《Advanced Photonics》2025年第1期1-1,共1页先进光子学(英文)

摘　　要：Year 2025 is recognized by the United Nations as the International Year of Quantum Science and Technology.This celebration is more than a symbolic milestone;it is a recognition of the profound impact quantum science is having across disciplines and applications.But quantum science has its roots firmly in optics.It all began with Max Planck's work on black body radiation.Planck's discovery of quantized energy levels laid the foundation for quantum theory.Albert Einstein further advanced the field with explanation of the photoelectric effect,demonstrating that light could be understood as discrete packets of energy,which we now call photons.Niels Bohr then developed a model of the atom that explained the emission spectrum of hydrogen.
