In particle physics, the coincidence method (or coincidence technique) is an experimental design through which particle detectors register two or more simultaneous measurements of a particular event through different interaction channels. Detection can be made by sensing the primary particle and/or through the detection of secondary reaction ...
In quantum physics, coincidence counting is used in experiments testing particle non-locality and quantum entanglement. In these experiments two or more particles are created from the same initial packet of energy, inexorably linking/entangling their physical properties.
The Philadelphia Index is conducted monthly by the Federal Reserve Bank of Philadelphia and questions voluntary participants on things such as unemployment, new orders, shipments, inventories, and prices paid. The report is released on the third Thursday of every month, making it the earliest such regional report which is released to investors.
There are many coincident economic indicators, such as Gross Domestic Product, industrial production, personal income and retail sales. A coincident index may be used to identify, after the fact, the dates of peaks and troughs in the business cycle. [6] There are four economic statistics comprising the Index of Coincident Economic Indicators: [7]
In physics and electrical engineering, a coincidence circuit or coincidence gate is an electronic device with one output and two (or more) inputs. The output activates only when the circuit receives signals within a time window accepted as at the same time and in parallel at both inputs.

In quantum mechanics and quantum field theory, the propagator is a function that specifies the probability amplitude for a particle to travel from one place to another in a given period of time, or to travel with a certain energy and momentum.
This count, either as a ratio of the total or normalized by dividing by the expected count for a random source model, is known as the index of coincidence, or IC or IOC [2] or IoC [3] for short. Because letters in a natural language are not distributed evenly , the IC is higher for such texts than it would be for uniformly random text strings.
