Quantum enhancement

Definition

Quantum enhancement refers to the improvement in measurement sensitivity or precision achieved through the utilization of quantum phenomena. This concept plays a crucial role in various applications, particularly in sensing technologies where it enables the detection of minute changes in physical systems, thus providing insights into molecular structures and dynamics that are otherwise challenging to observe.
