Conditional Spectroscopy via Non-Stationary Optical Homodyne Quantum State Tomography
Johannes Thewes, Carolin Lüders, Marc Aßmann
Continuous variable quantum state tomography is one of the most powerful techniques to study the properties of light fields in quantum optics. However, the need for a fixed phase r…
An eavesdropping attack on a trusted continuous-variable quantum random number generator
Johannes Thewes, Carolin Lüders, Marc Aßmann
Harnessing quantum processes is an efficient method to generate truly indeterministic random numbers, which are of fundamental importance for cryptographic protocols, security appl…
Real time monitoring at 100 kHz
Carolin Lüders, Johannes Thewes, Marc Aßmann
We introduce a technique to determine photon correlations of optical light fields in real time. The method is based on ultrafast phase-randomized homodyne detection and allows us t…
Deviations of the exciton level spectrum in cuprous oxide from the hydrogen series
Florian Schöne, Sjard-Ole Krüger, Peter Grünwald +7
Recent high-resolution absorption spectroscopy on excited excitons in cuprous oxide [Nature (London) 514, 343 (2014)] has revealed significant deviations of their spectrum from tha…
