A 698 nm laser system for excitation of fluorescent quantum light sources on a CubeSat mission
Sven Schwertfeger, Elisa Da Ros, Marcel Bursy +6
This manuscript reports on the development and qualification of an ECDL-based, fiber-coupled laser system at a wavelength of λ = 698 nm for space applications. We designed and deve…
QUICK -- Design of a satellite-based quantum light source for quantum communication and extended physical theory tests in space
Najme Ahmadi, Sven Schwertfeger, Philipp Werner +19
Modern quantum technologies have matured such that they can now be used in space applications, e.g., long-distance quantum communication. Here, we present the design of a compact t…
Realizing a Robust, Reconfigurable Active Quenching Design for Multiple Types of Single-Photon Avalanche Detectors
Subash Sachidananda, Prithvi Gundlapalli, Victor Leong +3
Most active quench circuits used for single-photon avalanche photodetectors (APDs) are designed either with discrete components which lack the flexibility of dynamically changing t…
Realizing a robust, reconfigurable active quenching design for multiple architectures of single-photon avalanche detectors
Subash Sachidananda, Prithvi Gundlapalli, Victor Leong +2
Most active quench circuits used for single-photon avalanche detectors are designed either with discrete components which lack the flexibility of dynamically changing the control p…
Realizing quantum nodes in space for cost-effective, global quantum communication: in-orbit results and next steps
Chithrabhanu Perumangatt, Tom Vergoossen, Alexander Lohrmann +6
Quantum sources and receivers operating on-board satellites are an essential building block for global quantumnetworks. SpooQy-1 is a satellite developed at the Centre for Quantum…
Entanglement demonstration on board a nano-satellite
Aitor Villar, Alexander Lohrmann, Xueliang Bai +14
Global quantum networks for secure communication can be realised using large fleets of satellites distributing entangled photon-pairs between ground-based nodes. Because the cost o…
Bias voltage Control of Avalanche Photo-Diode Using a Window Comparator
Subash Sachidananda, Alexander Ling
This work aims at controlling the bias voltage of APDs, used for single photon detection, with a micro-controller through pulse height comparison.
