Absolute frequency measurements of 85Rb nF7/2 Rydberg states using purely optical detection

, 2010
A three-step laser excitation scheme is used to make absolute frequency measurements of highly excited nF7/2 Rydberg states in 85Rb for principal quantum numbers n=33-100.

Experimental determination of the local optical conductivity of a semiconducting carbon nanotube and its modification at individual defects

, 2017
Measurements of optical properties at nanometre-level are of central importance for characterization of optoelectronic device. It was, however, hardly possible for the conventional light-probe measurements to determine the local optical properties from ...

Detecting Planets Around Very Low Mass Stars with the Radial Velocity Method

, 2009
The detection of planets around very low-mass stars with the radial velocity method is hampered by the fact that these stars are very faint at optical wavelengths where the most high-precision spectrometers operate.

Space Debris: Optical Measurements [PDF]

, 2020
Space debris is a major threat to the satellite infrastructure. A collision with even small particle, e.g. 1 cm of size, can cause a catastrophic event when the parent body, spacecraft or upper stage, will break up into hundreds of trackable fragments.

Implementing general measurements on linear optical and solid-state qubits

, 2012
We show a systematic construction for implementing general measurements on a single qubit, including both strong (or projection) and weak measurements. We mainly focus on linear optical qubits.
