Quantum Optics
The Poisson distribution is a probability distribution that describes the number of events occurring in a fixed interval of time or space, given that these events occur independently and with a known constant mean rate. It is particularly important in scenarios where events are rare or occur randomly, such as photon counting in quantum optics, where it models the statistics of detected photons. The Poisson distribution helps in understanding the behavior of photon emission and the performance of photon-number-resolving detectors.
congrats on reading the definition of Poisson Distribution. now let's actually learn it.
