High-rate multipartite quantum secret sharing with composable security
Russell M. J. Brooks, Joseph Ho, Joseph Niblo +5
Future quantum communication networks will conceivably support cryptographic tasks that require entanglement among more than two users. Quantum secret sharing is a prime example wh…
Strategy optimization for quantum conference key agreement in asymmetric star networks
Janka Memmen, Julia Kunzelmann, Nathan Walk +2
The distribution of entangled states is a core task for quantum networks facilitating quantum communication, and the use of multipartite entangled states comes with its own set of…
Certification of linear optical quantum state preparation
Riko Schadow, Naomi Spier, Stefan N. van den Hoven +6
Certification is important to guarantee the correct functioning of quantum devices. A key certification task is verifying that a device has produced a desired output state. In this…
Rigorous no-go theorems for heralded linear-optical state generation tasks
Deepesh Singh, Ryan J. Marshman, Luis Villegas-Aguilar +2
A major challenge in photonic quantum technologies is developing strategies to prepare suitable discrete-variable quantum states using simple input states, linear optics, and auxil…
Unifying communication paradigms in measurement-based delegated quantum computing
Fabian Wiesner, Jens Eisert, Anna Pappa
Delegated quantum computing (DQC) allows clients with low quantum capabilities to outsource computations to a server hosting a quantum computer. This process is often envisioned wi…
Coherently mitigating boson samplers with stochastic errors
Deepesh Singh, Ryan J. Marshman, Nathan Walk +3
Sampling experiments provide a viable route to show quantum advantages of quantum devices over classical computers in well-defined computational tasks. However, quantum devices suc…
Advantage of multi-partite entanglement for quantum cryptography over long and short ranged networks
Janka Memmen, Jens Eisert, Nathan Walk
The increasing sophistication of available quantum networks has seen a corresponding growth in the pursuit of multi-partite cryptographic protocols. Whilst the use of multi-partite…
ReQuSim: Faithfully simulating near-term quantum repeaters
Julius Wallnöfer, Frederik Hahn, Fabian Wiesner +2
Quantum repeaters have long been established to be essential for distributing entanglement over long distances. Consequently, their experimental realization constitutes a core chal…
Equivalence in delegated quantum computing
Fabian Wiesner, Jens Eisert, Anna Pappa
Delegated quantum computing (DQC) enables limited clients to perform operations that are outside their capabilities remotely on a quantum server. Protocols for DQC are usually set…
Anonymous conference key agreement in linear quantum networks
Jarn de Jong, Frederik Hahn, Jens Eisert +2
Sharing multi-partite quantum entanglement between parties allows for diverse secure communication tasks to be performed. Among them, conference key agreement (CKA), an extension o…
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…
Simulating quantum repeater strategies for multiple satellites
Julius Wallnöfer, Frederik Hahn, Mustafa Gündoğan +5
A global quantum repeater network involving satellite-based links is likely to have advantages over fiber-based networks in terms of long-distance communication, since the photon l…
Rate limits in quantum networks with lossy repeaters
Riccardo Laurenza, Nathan Walk, Jens Eisert +1
The derivation of ultimate limits to communication over certain quantum repeater networks have provided extremely valuable benchmarks for assessing near-term quantum communication…
Sharing classical secrets with continuous-variable entanglement: Composable security and network coding advantage
Nathan Walk, Jens Eisert
Secret sharing is a multi-party cryptographic primitive that can be applied to a network of partially distrustful parties for encrypting data that is both sensitive (it must remain…
Quantum network routing and local complementation
F. Hahn, A. Pappa, J. Eisert
Quantum communication between distant parties is based on suitable instances of shared entanglement. For efficiency reasons, in an anticipated quantum network beyond point-to-point…
Rates of multi-partite entanglement transformations and applications in quantum networks
A. Streltsov, C. Meignant, J. Eisert
The theory of the asymptotic manipulation of pure bipartite quantum systems can be considered completely understood: The rates at which bipartite entangled states can be asymptotic…
