Squeezed states are a special type of quantum state in which the uncertainty in one property, like position, is reduced at the expense of increased uncertainty in another property, such as momentum. This phenomenon is a key feature of quantum mechanics and is often used in fields like quantum optics and quantum information. These states are important for improving the precision of measurements, such as in quantum computing and gravitational wave detection. By squeezing the uncertainty, scientists can enhance the sensitivity of their instruments, allowing for more accurate observations and experiments in the quantum realm.
