Atomic quantum metrology with narrowband entangled and squeezed states of light 

Wolfgramm, Florian (Date of defense: 2012-06-29)

The use of light, especially of laser light, is in many cases the most sensitive way to perform measurements. However, the highest sensitivity that can be achieved with laser light as probe is bounded by the standard quantum ...

Nanoscale Coherent Control. Ultrafast dynamics of single molecules, individual light harvesting complexes and discrete nanoantennas at room temperature. 

Brinks, Daan (Date of defense: 2012-10-19)

Ultrafast pulses allow observation of molecular dynamics with femtosecond time resolution through pump probe experiments. However, averaging over an ensemble of molecules tends to wash out phase sensitive information, ...
