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…

Verified delegated quantum computation requires techniques beyond cut-and-choose

Fabian Wiesner, Anna Pappa

Delegated quantum computation enables a client with limited quantum capabilities to outsource computations to a more powerful quantum server while preserving correctness and privac…

Why quantum state verification cannot be both efficient and secure: a categorical approach

Fabian Wiesner, Ziad Chaoui, Diana Kessler +2

The advantage of quantum protocols lies in the inherent properties of the shared quantum states. These states are sometimes provided by sources that are not trusted, and therefore…

Why cut-and-choose quantum state verification cannot be both efficient and secure

Fabian Wiesner, Ziad Chaoui, Diana Kessler +2

Quantum state verification plays a vital role in many quantum cryptographic protocols, as it allows the use of quantum states from untrusted sources. While some progress has been m…

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…
