Quantum communication networks with defects in silicon carbide
Philipp Sohr, Philipp Koller, Sebastian Ecker +23
Quantum communication promises unprecedented capabilities enabled by the transmission of quantum states of light. However, current implementations face severe distance limitations…
Non-inertial motion dependent entangled Bell-state
Julius Arthur Bittermann, Matthias Fink, Marcus Huber +1
We show the targeted phase-manipulation of an entangled photonic Bell state via non-inertial motion. To this end, we place a very compact laboratory, consisting of a SPDC source an…
Photonic entanglement during a zero-g flight
Julius Bittermann, Lukas Bulla, Sebastian Ecker +6
Quantum technologies have matured to the point that we can test fundamental quantum phenomena under extreme conditions. Specifically, entanglement, a cornerstone of modern quantum…
Strategies for achieving high key rates in satellite-based QKD
Sebastian Ecker, Bo Liu, Johannes Handsteiner +6
Quantum key distribution (QKD) is a pioneering quantum technology on the brink of widespread deployment. Nevertheless, the distribution of secret keys beyond a few 100 kilometers a…
Hong-Ou-Mandel interferometry on a biphoton beat note
Yuanyuan Chen, Matthias Fink, Fabian Steinlechner +2
Hong-Ou-Mandel interference, the fact that identical photons that arrive simultaneously on different input ports of a beam splitter bunch into a common output port, can be used to…
Entanglement-enhanced optical gyroscope
Matthias Fink, Fabian Steinlechner, Johannes Handsteiner +3
Fiber optic gyroscopes (FOG) based on the Sagnac effect are a valuable tool in sensing and navigation and enable accurate measurements in applications ranging from spacecraft and a…
Satellite-relayed intercontinental quantum network
Sheng-Kai Liao, Wen-Qi Cai, Johannes Handsteiner +33
We perform decoy-state quantum key distribution between a low-Earth-orbit satellite and multiple ground stations located in Xinglong, Nanshan, and Graz, which establish satellite-t…
Quantum Communication Uplink to a 3U CubeSat: Feasibility & Design
Sebastian Philipp Neumann, Siddarth Koduru Joshi, Matthias Fink +8
Satellites are the efficient way to achieve global scale quantum communication (Q.Com) because unavoidable losses restrict fiber based Q.Com to a few hundred kilometers. We demonst…
Nanobob: A Cubesat Mission Concept For Quantum Communication Experiments In An Uplink Configuration
Erik Kerstel, Arnaud Gardelein, Mathieu Barthelemy +23
We present a ground-to-space quantum key distribution (QKD) mission concept and the accompanying feasibility study for the development of the low earth orbit CubeSat payload. The q…
Distribution of high-dimensional entanglement via an intra-city free-space link
Fabian Steinlechner, Sebastian Ecker, Matthias Fink +5
Quantum entanglement is a fundamental resource in quantum information processing and its distribution between distant parties is a key challenge in quantum communications. Increasi…
Cosmic Bell Test: Measurement Settings from Milky Way Stars
Johannes Handsteiner, Andrew S. Friedman, Dominik Rauch +17
Bell's theorem states that some predictions of quantum mechanics cannot be reproduced by a local-realist theory. That conflict is expressed by Bell's inequality, which is usually d…
Experimental test of photonic entanglement in accelerated reference frames
Matthias Fink, Ana Rodriguez-Aramendia, Johannes Handsteiner +7
The quantization of the electromagnetic field has successfully paved the way for the development of the Standard Model of Particle Physics and has established the basis for quantum…
Twisted Light Transmission over 143 kilometers
Mario Krenn, Johannes Handsteiner, Matthias Fink +4
Spatial modes of light can potentially carry a vast amount of information, making them promising candidates for both classical and quantum communication. However, the distribution…
Twisted photon entanglement through turbulent air across Vienna
Mario Krenn, Johannes Handsteiner, Matthias Fink +2
Photons with a twisted phase front can carry a discrete, in principle unbounded amount of orbital angular momentum (OAM). The large state space allows for complex types of entangle…
Teleportation of entanglement over 143 km
Thomas Herbst, Thomas Scheidl, Matthias Fink +4
As a direct consequence of the no-cloning theorem, the deterministic amplification as in classical communication is impossible for quantum states. This calls for more advanced tech…
Communication with spatially modulated Light through turbulent Air across Vienna
Mario Krenn, Robert Fickler, Matthias Fink +5
The transverse spatial modes of light offer a large state-space with interesting physical properties. For exploiting it in future long-distance experiments, spatial modes will have…
