Daylight operation of a free space, entanglement-based quantum key distribution system
Matthew P. Peloso, Ilja Gerhardt, Caleb Ho +2
Many quantum key distribution (QKD) implementations using a free space transmission path are restricted to operation at night time in order to distinguish the signal photons used f…
Coherent State Preparation and Observation of Rabi Oscillations in a Single Molecule
Ilja Gerhardt, Gert Wrigge, Gert Zumofen +3
We report on the excitation of single molecules via narrow zero-phonon transitions using short laser pulses. By monitoring the Stokes-shifted fluorescence, we studied the excited s…
Exploring the limits of single emitter detection in fluorescence and extinction
Gert Wrigge, Jaesuk Hwang, Ilja Gerhardt +2
We present an experimental comparison and a theoretical analysis of the signal-to-noise ratios in fluorescence and extinction spectroscopy of a single emitter. We show that extinct…
