(spectroscopy)
The shortest wavelength present in a continuous x-ray spectrum. Also known as boundary wavelength; end radiation.

quantum limit

The shortest possible wavelength that can be transmitted or sensed in an optical system. For example, lasers and optical receivers, as well as the human eye, have a quantum limit.

A possible experiment requiring sensitivities beyond the standard quantum limit was suggested.
Kuzyk was the first to predict the fundamental physical limits on the nonlinear properties of molecular materials in 2000 and says that by approaching the quantum limit, the University of Toronto-Carleton team has succeeded where all other researchers have failed.
The combination of moderate resonant frequencies (tens of megahertz) and ultralow temperatures (sub-millikelvin) will enable the quantum limit of the mechanical oscillator to be reached while also allowing the state of the resonator to be probed and manipulated on experimentally-accessible timescales.
