The Influence of Experimental Imperfections on Photonic GHZ State Generation
Fabian Wiesner, Helen M. Chrzanowski, Gregor Pieplow +3
While the advantages of photonic quantum computing, including direct compatibility with communication, are apparent, several imperfections such as loss and distinguishability prese…
Limitations of nearest-neighbour quantum networks
Frederik Hahn, Axel Dahlberg, Jens Eisert +1
Quantum communication research has in recent years shifted to include multi-partite networks for which questions of quantum network routing naturally emerge. To understand the pote…
Anonymous and secret communication in quantum networks
Christopher Thalacker, Frederik Hahn, Jarn de Jong +2
Secure communication is one of the key applications of quantum networks. In recent years, following the demands for identity protection in classical communication protocols, the ne…
Anonymous Quantum Conference Key Agreement
Frederik Hahn, Jarn de Jong, Anna Pappa
Conference Key Agreement (CKA) is a cryptographic effort of multiple parties to establish a shared secret key. In future quantum networks, generating secret keys in an anonymous wa…
Anonymous Conference Key Agreement in Quantum Networks
Frederik Hahn, Jarn de Jong, Christopher Thalacker +3
Quantum Conference Key Agreement (CKA) is a cryptographic effort of multiple parties to establish a shared secret key. While bipartite quantum key distribution protocols are also u…
Definitions and Analysis of Quantum E-voting Protocols
Myrto Arapinis, Elham Kashefi, Nikolaos Lamprou +1
Recent advances indicate that quantum computers will soon be reality. Motivated by this ever more realistic threat for existing classical cryptographic protocols, researchers have…
Tsirelson's bound and Landauer's principle in a single-system game
Luciana Henaut, Lorenzo Catani, Dan E. Browne +2
We introduce a simple single-system game inspired by the Clauser-Horne-Shimony-Holt (CHSH) game. For qubit systems subjected to unitary gates and projective measurements, we prove…
Classical multiparty computation using quantum resources
Marco Clementi, Anna Pappa, Andreas Eckstein +3
In this work, we demonstrate a new way to perform classical multiparty computing amongst parties with limited computational resources. Our method harnesses quantum resources to inc…
Experimental Verification of Multipartite Entanglement in Quantum Networks
W. McCutcheon, A. Pappa, B. A. Bell +9
Multipartite entangled states are a fundamental resource for a wide range of quantum information processing tasks. In particular, in quantum networks it is essential for the partie…
Multiparty Delegated Quantum Computing
Elham Kashefi, Anna Pappa
Quantum computing has seen tremendous progress in the past years. However, due to limitations in scalability of quantum technologies, it seems that we are far from constructing uni…
Attacks exploiting deviation of mean photon number in quantum key distribution and coin tossing
Shihan Sajeed, Igor Radchenko, Sarah Kaiser +5
The security of quantum communication using a weak coherent source requires an accurate knowledge of the source's mean photon number. Finite calibration precision or an active mani…
Nonlocality and conflicting interest games
Anna Pappa, Niraj Kumar, Thomas Lawson +4
Nonlocality enables two parties to win specific games with probabilities strictly higher than allowed by any classical theory. Nevertheless, all known such examples consider games…
Reliable experimental quantification of bipartite entanglement without reference frames
Thomas Lawson, Anna Pappa, Boris Bourdoncle +3
Simply and reliably detecting and quantifying entanglement outside laboratory conditions will be essential for future quantum information technologies. Here we address this issue b…
Experimental plug&play quantum coin flipping
Anna Pappa, Paul Jouguet, Thomas Lawson +5
Performing complex cryptographic tasks will be an essential element in future quantum communication networks. These tasks are based on a handful of fundamental primitives, such as…
Multipartite entanglement verification resistant against dishonest parties
Anna Pappa, André Chailloux, Stephanie Wehner +2
Future quantum information networks will likely consist of quantum and classical agents, who have the ability to communicate in a variety of ways with trusted and untrusted parties…
Practical Quantum Coin Flipping
Anna Pappa, André Chailloux, Eleni Diamanti +1
In this article we show for the first time that quantum coin flipping with security guarantees that are strictly better than any classical protocol is possible to implement with cu…
