Central European Workshop on Quantum Optics (CEWQO) is one of the most popular annual meetings for scientists from Europe and beyond. Each year it is organized in a different place and this year its 28th iteration returns to the Central Europe. Let us meet in Olomouc (1st—5th of July, 2024) and discuss the broad canvass of Quantum Optics, from the fundamentals to the technological applications.
