|---|---|---|---|
| A quantum cloning game with applications to quantum position verification | TQC 2025 | regular | Léo Colisson Palais, Florian Speelman |

| Making Existing Quantum Position Verification Protocols Secure Against Arbitrary Transmission Loss | QIP 2024 | regular | ▸Rene Allerstorfer, Andreas Bluhm, Harry Buhrman, Matthias Christandl, Florian Speelman, Philip Verduyn Lunel |
| Single-qubit loss-tolerant quantum position verification protocol secure against entangled attackers | QCRYPT 2023 | regular ▸ presenter | Florian Speelman |
We give a tight characterization of the relation between loss-tolerance and error rate of the most popular protocol for quantum position verification (QPV), which is based on BB84 states, and generalizations of this protocol. Combining it with classical information, we show for the first time a fault-tolerant protocol that is secure against attackers who pre-share a linear amount of entanglement (in the classical information), arbitrarily slow quantum information and that tolerates a certain amount of photon loss. We also extend this analysis to the case of more than two bases, showing even stronger loss-tolerance for that case. Finally, we show that our techniques can be applied to improve the analysis of one-sided device-independent QKD protocols. |
