A new quantum sensor can analyze the full spectrum of radio frequency and real-world signals, unleashing new potentials for soldier communications, spectrum awareness and electronic warfare. Army ...

We present mass-correlated rotational alignment spectroscopy, based on the optical excitation of a coherent rotational quantum wave and the observation of temporal wave interferences in a mass ...

Raman spectroscopy is an analytical technique that allows for the assessment of molecular structure and the identification of materials by examining the rotational and vibrational modes of molecules.

A project at Max-Planck-Institute of Quantum Optics (MPQ) and Ludwig Maximilian University of Munich (LMU) has successfully probed complex optical spectra at high resolution and very low light levels.
