Security-proof framework for two-way Gaussian quantum-key-distribution protocols

Two-way Gaussian protocols have the potential to increase quantum key distribution (QKD) protocols' secret-key rates by orders of magnitudes [Phys. Rev. A 94, 012322 (2016)2469-992610.1103/PhysRevA.94.012322]. Security proofs for two-way protocols, however, are underdeveloped at present. In thi...
