Ad-hoc hybrid-heterogeneous metropolitan-range quantum key distribution network
Matthias Goy, Jan Krause, Ömer Bayraktar +37
This paper presents the development and implementation of a versatile ad-hoc metropolitan-range Quantum Key Distribution (QKD) network. The approach presented integrates various ty…
Adjustable spatial filter for optimal free-space quantum communication round the clock
Andrej Kržič, Nico Döll, Uday Chandrashekara +2
Free-space quantum communication in daylight relies crucially on spatial filtering. The optimal filter configuration, however, depends on ever-changing link conditions. To this end…
Towards metropolitan free-space quantum networks
Andrej Kržič, Sakshi Sharma, Christopher Spiess +18
Quantum communication has seen rapid progress towards practical large-scale networks, with quantum key distribution (QKD) spearheading this development. While fibre based systems h…
Super-Resolution of PROBA-V Images Using Convolutional Neural Networks
Marcus Märtens, Dario Izzo, Andrej Krzic +1
ESA's PROBA-V Earth observation satellite enables us to monitor our planet at a large scale, studying the interaction between vegetation and climate and provides guidance for impor…
Tempering Rayleigh's curse with PSF shaping
M. Paur, B. Stoklasa, J. Grover +4
It has been argued that, for a spatially invariant imaging system, the information one can gain about the separation of two incoherent point sources decays quadratically to zero wi…
Optimal measurements for quantum spatial superresolution
J. Rehacek, Z. Hradil, D. Koutny +3
We construct optimal measurements, achieving the ultimate precision predicted by quantum theory, for the simultaneous estimation of centroid, separation, and relative intensities o…
Multiparameter Quantum Metrology of Incoherent Point Sources: Towards Realistic Superresolution
J. Rehacek, Z. Hradil, B. Stoklasa +4
We establish the multiparameter quantum Cramér-Rao bound for simultaneously estimating the centroid, the separation, and the relative intensities of two incoherent optical point so…
