Abstract

En 中文

• Proposes a flexible multi-party QHE scheme based on graph states. • Eliminates amplitude and phase damping noise simultaneously. • Uses quantum sealed-bid auctions for dynamic node selection. • Supports participant addition and removal without restarting. • Achieves full homomorphism and information-theoretic security.
