Experimental demonstration of graph-state quantum secret sharing

Understand

Distributed quantum communication and quantum computing offer many new opportunities for quantum information processing.

• Here networks based on highly nonlocal quantum resources with complex entanglement structures have been proposed for distributing, sharing and processing quantum information.
• Graph states in particular have emerged as powerful resources for such tasks using measurement-based techniques.
• We report an experimental demonstration of graph-state quantum secret sharing, an important primitive for a quantum network.
