Pulse shape optimization against Doppler shifts and delays in optical quantum communication
Emanuel Schlake, Roy Barzel, Dennis Rätzel +1
High relative velocities and large distances in space-based quantum communication with satellites in lower earth orbits can lead to significant Doppler shifts and delays of the sig…

Observer dependence of photon bunching: The influence of the relativistic redshift on Hong-Ou-Mandel interference
Roy Barzel, David Edward Bruschi, Andreas W. Schell +1
We study the influence of the relativistic redshift on Hong-Ou-Mandel (HOM) interference, and present a genuine quantum test of general relativity. We use Glauber's theory of quant…

Delayed transition to coherent emission in nanolasers with extended gain media
Frederik Lohof, Roy Barzel, Paul Gartner +1
The realization of high- lasers is one of the prime applications of cavity-QED promising ultra-low thresholds, integrability and reduced power consumption in the field of \texti…
