High-dimensional quantum key distribution with resource-efficient detection
Maciej Ogrodnik, Adam Widomski, Dagmar Bruß +7
While quantum key distribution (QKD) based on two-dimensional (qubit) encoding is a mature, field-tested technology, its performance is lacking for many cryptographic applications.…
Quantum Key Distribution with Basis-Dependent Detection Probability
Federico Grasselli, Giovanni Chesi, Nathan Walk +7
Quantum Key Distribution (QKD) is a promising technology for secure communication. Nevertheless, QKD is still treated with caution in certain contexts due to potential gaps between…
Quantum-private distributed sensing
Joseph Ho, Jonathan W. Webb, Russell M. J. Brooks +3
Quantum networks can enhance both security and privacy conditions for multi-user communication, delegated computation, and distributed sensing tasks. An example quantum protocol is…
Experimental anonymous quantum conferencing
Jonathan W. Webb, Joseph Ho, Federico Grasselli +4
Anonymous quantum conference key agreement (AQCKA) allows a group of users within a network to establish a shared cryptographic key without revealing their participation. Although…
Satellite-Based Quantum Key Distribution in the Presence of Bypass Channels
Masoud Ghalaii, Sima Bahrani, Carlo Liorni +9
The security of prepare-and-measure satellite-based quantum key distribution (QKD), under restricted eavesdropping scenarios, is addressed. We particularly consider cases where the…
Overcoming fundamental bounds on quantum conference key agreement
Giacomo Carrara, Gláucia Murta, Federico Grasselli
Twin-Field Quantum Key Distribution (TF-QKD) enables two distant parties to establish a shared secret key, by interfering weak coherent pulses (WCPs) in an intermediate measuring s…
Boosting device-independent cryptography with tripartite nonlocality
Federico Grasselli, Gláucia Murta, Hermann Kampermann +1
Device-independent (DI) protocols, such as DI conference key agreement (DICKA) and DI randomness expansion (DIRE), certify private randomness by observing nonlocal correlations whe…
Conference key agreement in a quantum network
Alexander Pickston, Joseph Ho, Andrés Ulibarrena +6
Quantum conference key agreement (QCKA) allows multiple users to establish a secure key from a shared multi-partite entangled state. In a quantum network, this protocol can be effi…
Secure Anonymous Conferencing in Quantum Networks
Federico Grasselli, Gláucia Murta, Jarn de Jong +4
Users of quantum networks can securely communicate via so-called (quantum) conference key agreement --making their identities publicly known. In certain circumstances, however, com…
Entropy bounds for multiparty device-independent cryptography
Federico Grasselli, Gláucia Murta, Hermann Kampermann +1
Multiparty quantum cryptography based on distributed entanglement will find its natural application in the upcoming quantum networks. The security of many multipartite device-indep…
Quantum Conference Key Agreement: A Review
Gláucia Murta, Federico Grasselli, Hermann Kampermann +1
Conference key agreement (CKA), or multipartite key distribution, is a cryptographic task where more than two parties wish to establish a common secret key. A composition of bipart…
Experimental quantum conference key agreement
Massimiliano Proietti, Joseph Ho, Federico Grasselli +3
Quantum networks will provide multi-node entanglement over long distances to enable secure communication on a global scale. Traditional quantum communication protocols consume pair…
Conference key agreement with single-photon interference
Federico Grasselli, Hermann Kampermann, Dagmar Bruß
The intense research activity on Twin-Field (TF) quantum key distribution (QKD) is motivated by the fact that two users can establish a secret key by relying on single-photon inter…
Asymmetric twin-field quantum key distribution
Federico Grasselli, Alvaro Navarrete, Marcos Curty
Twin-Field (TF) quantum key distribution (QKD) is a major candidate to be the new benchmark for far-distance QKD implementations, since its secret key rate can overcome the repeate…
Practical decoy-state method for twin-field quantum key distribution
Federico Grasselli, Marcos Curty
Twin-Field (TF) quantum key distribution (QKD) represents a novel QKD approach whose principal merit is to beat the point-to-point private capacity of a lossy quantum channel, than…
Finite-key effects in multi-partite quantum key distribution protocols
Federico Grasselli, Hermann Kampermann, Dagmar Bruß
We analyze the security of two multipartite quantum key distribution (QKD) protocols, specifically we introduce an -partite version of the BB84 protocol and we discuss the -p…
Continuous-variable quantum probes for structured environments
Matteo Bina, Federico Grasselli, Matteo G. A. Paris
We address parameter estimation for complex/structured systems and suggest an effective estimation scheme based on continuous-variables quantum probes. In particular, we investigat…
