Quantum Sensors and Metrology
Unitary operators are linear operators that preserve the inner product in a Hilbert space, ensuring that quantum states remain normalized during transformations. These operators play a crucial role in quantum mechanics, particularly in describing the evolution of quantum states and the behavior of observables. Because unitary operators maintain the overall probability structure of quantum systems, they are essential for understanding processes such as quantum measurement and time evolution.
