Early determinations of the speed of light, based on astronomical observations or terrestrial time-of-flight experiments, were largely superseded in the 1940's by measurements of the frequency and wavelength of microwave radiation. The results were limited by the uncertainty in the wavelength measuremen...

Techniques that use quantum interference effects are being actively investigated to manipulate the optical properties of quantum systems1. One such example is electromagnetically induced transparency, a quantum effect that permits the propagation of light pulses through an otherwise opaque medium2, 3, 4,...

Time series are sequences of pairs (t[i], x[i]) where the real-valued time stamps t[i] are linearly ordered and their corresponding values x[i] are quantities measured at time t[i]. If all timestamps are equally spaced, i.e., t[i+1]-t[i] = const for all i, then you can...
