Contribution

It introduces the concept of blind quantum computation in the ancilla-driven model, which had not been previously studied, and analyzes its feasibility and constraints.

Findings

Demonstrates the possibility of blind quantum computation in the ancilla-driven model

Identifies limitations and challenges specific to this hybrid approach

Expands understanding of secure quantum computation protocols

Abstract

Blind quantum computation is a new quantum secure protocol, which enables Alice who does not have enough quantum technology to delegate her computation to Bob who has a fully-fledged quantum power without revealing her input, output and algorithm. So far, blind quantum computation has been considered only for the circuit model and the measurement-based model. Here we consider the possibility and the limitation of blind quantum computation in the ancilla-driven model, which is a hybrid of the circuit and the measurement-based models.
