  • There are different quantum algorithms developed for the security of current cryptographic concepts. Here the authors demonstrate a method to perform quantum-secured digital payments using unforgeable quantum cryptograms over an optical fiber link and verify the information-theoretic security.

  • Quantum-enhanced versions of weak coin flipping (a cryptographic primitive where two mistrustful parties agree on a random bit while favouring opposite outcomes) have been proposed in the past but never realised. Here, the authors fill this gap by improving on a previous proposal and implementing it with single photons in a fibre-based setup.
