Fading channel estimation for free-space continuous-variable secure quantum communication
László Ruppert, Christian Peuntinger, Bettina Heim +6
We investigate estimation of fluctuating channels and its effect on security of continuous-variable quantum key distribution. We propose a novel estimation scheme which is based on…
Stabilization of transmittance fluctuations caused by beam wandering in continuous-variable quantum communication over free-space atmospheric channels
Vladyslav C. Usenko, Christian Peuntinger, Bettina Heim +6
Transmittance fluctuations in turbulent atmospheric channels result in quadrature excess noise which limits applicability of continuous-variable quantum communication. Such fluctua…
Space QUEST mission proposal: Experimentally testing decoherence due to gravity
Siddarth Koduru Joshi, Jacques Pienaar, Timothy C. Ralph +42
Models of quantum systems on curved space-times lack sufficient experimental verification. Some speculative theories suggest that quantum properties, such as entanglement, may exhi…
High-Dimensional Intra-City Quantum Cryptography with Structured Photons
Alicia Sit, Frédéric Bouchard, Robert Fickler +11
Quantum key distribution (QKD) promises information-theoretically secure communication, and is already on the verge of commercialization. Thus far, different QKD protocols have bee…
Quantum-limited measurements of optical signals from a geostationary satellite
Kevin Günthner, Imran Khan, Dominique Elser +13
The measurement of quantum signals that traveled through long distances is of fundamental and technological interest. We present quantum-limited coherent measurements of optical si…
Attacks on practical quantum key distribution systems (and how to prevent them)
Nitin Jain, Birgit Stiller, Imran Khan +3
With the emergence of an information society, the idea of protecting sensitive data is steadily gaining importance. Conventional encryption methods may not be sufficient to guarant…
