What is Coherent addition?

Coherent states have been introduced in a physical context, first as quasi-classical states in quantum mechanics, then as the backbone of quantum optics and they are described in that spirit...

Rotating-polarization coherent anti-Stokes Raman spectroscopy, is a particular implementation of the coherent anti-Stokes Raman spectroscopy. RP-CARS takes advantage of polarization-dependent selection rules in order to gain information about molecule orientation...

Coherent control is a quantum mechanics-based method for controlling dynamical processes by light. The basic principle is to control quantum interference phenomena, typically by shaping the phase of laser pulses....

In mathematics, especially in algebraic geometry and the theory of complex manifolds, coherent sheaf cohomology is a technique for producing functions with specified properties. Many geometric questions can be formulated...
