This study introduces a novel quantum secret sharing scheme that masks quantum states within multipartite systems. The proposed method enhances security and implementation ease for quantum information sharing.

Area of Science:

  • Quantum Information Science
  • Quantum Cryptography

Background:

  • Quantum secret sharing (QSS) is crucial for secure quantum communication.
  • Existing QSS schemes often face limitations in flexibility and implementation.

Purpose of the Study:

  • To propose a novel and authenticable quantum secret sharing scheme.
  • To enhance the security and practicality of sharing quantum states.

Main Methods:

  • Constructing quantum states using orthogonal arrays and generalizing to multi-body systems.
  • Designing a masking process for quantum states within multipartite quantum systems.
  • Developing a QSS scheme with special access structures based on the masking process.

Main Results:

  • Successfully shared an unknown quantum state among participants using a masked multi-particle entangled state.
