Asymmetric Quantum Secure Multi-Party Computation With Weak Clients Against Dishonest Majority. (arXiv:2303.08865v1 [quant-ph])

Secure multi-party computation (SMPC) protocols allow several parties that
distrust each other to collectively compute a function on their inputs. In this
paper, we introduce a protocol that lifts classical SMPC to quantum SMPC in a
composably and statistically secure way, even for a single honest party. Unlike
previous quantum SMPC protocols, our proposal only requires very limited
quantum resources from all but one party; it suffices that the weak parties,
i.e. the clients, are able to prepare single-qubit states …
