Demonstrates one protocol with two implementation, [[two copies of single photon]] method and [[decoy state]] method. First uses single qubit photons in three bases; Private key: classical description of states, Public key: pair of [[non-orthogonal states]] in any two of the three bases. '''Requires''' authenticated classical channels, [[polarisation measurement]] in three bases, [[Unambiguous State Discrimination (USD)]] (State Elimination), uses quantum correlations to check authentication. Decoy State method uses [[phase-randomised weak coherent states]], [[50:50 Beam Splitter (BS)]], [[Unconditionally Secure]] [[Network Stage: Prepare and Measure]]. | #[https://www.researchgate.net/publication/280062082_Practical_Quantum_Digital_Signature YFC (2016)] first QDS scheme without authenticated (trusted) quantum channels.
