Can you send a light pulse consisting of |n=0> , e.e. vacuum state, and what is the physical difference between sending zero photons and sending no photons?
A |n=0> photon number state refers to a quantum state in which there are no photons present in a given system. This state is often used as a reference state for comparison with other states that contain a specific number of photons.
A |n=0> photon number state can be created by removing all photons from a system through a process known as photon annihilation. This can be done using specialized equipment, such as beam splitters and detectors, in a controlled environment.
The |n=0> photon number state is significant in quantum mechanics as it serves as a reference state for other photon number states. It also helps to illustrate the concept of quantization in quantum physics, where energy is not continuous but exists in discrete units.
Yes, a |n=0> photon number state can exist in nature. In fact, most systems in the universe have a |n=0> photon number state as their ground state, meaning it is the lowest energy state of the system.
A |n=0> photon number state can be indirectly measured by detecting the absence of photons in a given system. This can be done using a variety of techniques, such as optical detection methods or photoelectric effect measurements.
