Coherent control is a technique used in quantum mechanics and optics to manipulate the behavior of particles, such as atoms or photons, using tailored light fields. By applying specific light pulses, researchers can influence the quantum states of these particles, allowing for precise control over their dynamics and interactions. This method has applications in various fields, including quantum computing, where it can help in the development of qubits, and laser technology, enhancing the efficiency of lasers. Coherent control enables scientists to explore new phenomena and improve technologies that rely on quantum mechanics.
