Coherent state - Wikipedia
In physics, specifically in quantum mechanics, a coherent state is the specific quantum state of the quantum harmonic oscillator, often described as a state that has dynamics most closely resem bling the oscillatory behavior of a classical harmonic oscillator. It was the first example of quantum dynamics when Erwin SchrÃ¶dinger derived it in 1926, while searching for solutions of the SchrÃ¶dinger equ

Chernoff bound - Wikipedia
In probability theory, a Chernoff bound is an exponentially decreasing upper bound on the tail of a random variable based on its moment generating function. The minimum of all such exponential bounds forms the Chernoff or Chernoff-CramÃ©r bound, which may decay faster than exponential (e.g. sub-Gaussian).[1][2] It is especially useful for sums of independent random variables, such as sums of Bernou

Bell's theorem - Wikipedia
"Bell inequality" redirects here. For the related experiments, see Bell test. Bell's theorem is a term encompassing a number of closely related results in physics, all of which determine that quantum mechanics is incompatible with local hidden-variable theories, given some basic assumptions about the nature of measurement. "Local" here refers to the principle of locality, the idea that a particle
