Deployment of Entanglement-Based QKD in Financial Infrastructure
Mirela Selimović, Roman Solar, Jonathan Gruner +6
We demonstrate the feasibility of entanglement-based quantum key distribution (eQKD) in high-security financial infrastructure over a 22 km fiber link with 8 dB loss between two da…
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…
Distribution of genuine high-dimensional entanglement over 10.2 km of noisy metropolitan atmosphere
Lukas Bulla, Kristian Hjorth, Oskar Kohout +9
In a recent quantum key distribution experiment, high-dimensional protocols were used to show an improved noise resistance over a 10.2 km free-space channel. One of the unresolved…
Spatial and spectral characterization of photon pairs at telecommunication-wavelength from type-0 spontaneous parametric down-conversion
Evelyn A. Ortega, Jorge Fuenzalida, Mirela Selimovic +7
The thorough characterization of entangled-photon sources is vital for their optimal use in quantum communication. However, this task is not trivial at telecommunication wavelength…
Non-local temporal interferometry for highly resilient free-space quantum communication
Lukas Bulla, Matej Pivoluska, Kristian Hjorth +9
Entanglement distribution via photons over long distances enables many applications, including quantum key distribution (QKD), which provides unprecedented privacy. The inevitable…
Continuous entanglement distribution over a transnational 248 km fibre link
Sebastian Philipp Neumann, Alexander Buchner, Lukas Bulla +2
Entanglement is the basis of many quantum applications. The technically most mature of them, quantum key distribution, harnesses quantum correlations of entangled photons to produc…
Unconditionally secure digital signatures implemented in an 8-user quantum network
Yoann Pelet, Ittoop Vergheese Puthoor, Natarajan Venkatachalam +11
The ability to know and verifiably demonstrate the origins of messages can often be as important as encrypting the message itself. Here we present an experimental demonstration of…
Experimental entanglement generation for quantum key distribution beyond 1 Gbit/s
Sebastian Philipp Neumann, Mirela Selimovic, Martin Bohmann +1
Top-performance sources of photonic entanglement are an indispensable resource for many applications in quantum communication, most notably quantum key distribution. However, up to…
A model for optimizing quantum key distribution with continuous-wave pumped entangled-photon sources
Sebastian Philipp Neumann, Thomas Scheidl, Mirela Selimovic +4
Quantum Key Distribution (QKD) allows unconditionally secure communication based on the laws of quantum mechanics rather then assumptions about computational hardness. Optimizing t…
Scalable authentication and optimal flooding in a quantum network
Naomi R. Solomons, Alasdair I. Fletcher, Djeylan Aktas +11
The global interest in quantum networks stems from the security guaranteed by the laws of physics. Deploying quantum networks means facing the challenges of scaling up the physical…
Experimental implementation of secure anonymous protocols on an eight-user quantum network
Zixin Huang, Siddarth Koduru Joshi, Djeylan Aktas +12
Anonymity in networked communication is vital for many privacy-preserving tasks. Secure key distribution alone is insufficient for high-security communications, often knowing who t…
A low-noise single-photon detector for long-distance free-space quantum communication
Elena Anisimova, Dmitri Nikulov, Simeng Simone Hu +5
We build and test a single-photon detector based on a Si avalanche photodiode Excelitas 30902SH thermoelectrically cooled to -100 deg. C. Our detector has dark count rate below 1 H…
