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…
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…
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…
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…
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…
