Multi-agent blind quantum computation without universal cluster state. (arXiv:2206.13330v2 [quant-ph] UPDATED)

Blind quantum computation (BQC) protocols enable quantum algorithms to be
executed on third-party quantum agents while keeping the data and algorithm
confidential. The previous proposals for measurement-based BQC require
preparing a highly entangled cluster state. In this paper, we show that such a
requirement is not necessary. Our protocol only requires pre-shared bell pairs
between delegated quantum agents, and there is no requirement of any classical
or quantum information exchange between agents during the execution. Our
proposal requires fewer quantum …
