# [https://arxiv.org/abs/quant-ph/0105032 GC-QDS (2001)] uses [[quantum one way function]] f(); Private keys: classical input x, Public keys: quantum output f(x). '''Requires''' quantum memory, quantum one way function, authenticated quantum and classical channels, [[SWAP Test]] (universal quantum computer). [[Unconditionally Secure]]. [[Network Stage: Quantum Memory]]
#[https://arxiv.org/abs/quant-ph/0601130 ACJ (2006)] discusses coherent states comparison with a QDS scheme outlined in the last section. Protocol uses the same protocol as (2) but replaces qubits with [[coherent states]], thus replacing SWAP-Test with [[Coherent State Comparison]]. Additionally, it also requires quantum memory, authenticated quantum and classical channels, [[multiports]]. [[Unconditionally Secure]], [[Network Stage: Quantum Memory]]
#[https://arxiv.org/abs/1309.1375 DWA (2013)] first QDS scheme without quantum memory based on [https://arxiv.org/abs/quant-ph/0601130 (3)]. '''Requires''' [[Coherent States]], authenticated quantum and classical channels, [[multiports]], [[Unambiguous State Discrimination (USD)]] (State Elimination), no symmetrisation required. [[Unconditionally Secure]]. [[Network Stage: Prepare and Measure]]

#[https://journals.aps.org/pra/abstract/10.1103/PhysRevA.90.042335 AL (2014)] Establishes coherent state mapping of (2). Replaces SWAP Test with beam splitters. Uses [[Unambiguous State Discrimination (USD)]] (State Elimination). '''Requires''' [[Phase encoded Coherent states]], [[Balanced Beam Splitters]]. No explicit security proof provided.

#[https://www.sciencedirect.com/science/article/pii/S0030402617308069 SWZY (2017)] Discusses an attack and suggests corrections on existing QDS scheme using single qubit rotations. Protocol uses rotation, qubits, [[one-way hash function]]; Private keys: angle of rotation, Public keys: string of rotated quantum states. '''Requires''' [[random number generator]], [[one-way hash function]], quantum memory, key distribution. [[Computationally Secure]], [[Third Network Stage: Quantum Memory|Third Network Stage (Quantum Memory)]]
