Coherent control

Coherent control is a technique used to manipulate molecular and atomic processes by precisely shaping the phases of their underlying quantum waves. Think of it as guiding a symphony of tiny particles, like electrons and atoms, so that their combined behavior results in desired outcomes—such as breaking a molecule into specific parts or initiating a chemical reaction. This is achieved using tailored light pulses that interfere constructively or destructively, allowing scientists to steer reactions with high precision. Essentially, coherent control harnesses the wave-like nature of quantum systems to influence physical and chemical transformations in a controlled manner.
