  1. A single-qubit position verification protocol that is secure against multi-qubit attacks (2022) doi.org

    Shows a robust linear lower bound on the dimension of the attack resource state.

  2. Quantum position verification in bounded-attack-frequency model (2016) doi.org

    Considers BB84 QPV with non-simultaneous arrival times of input information at the prover (the basis being encoded in which side arrived first). Discusses the general port-based attack in this setting.

  3. On the role of quantum communication and loss in attacks on quantum position verification (2022) arxiv.org

    Proves a 3/4 upper bound on the success probability of unentangled attacks.

  4. Continuous-variable quantum position verification secure against entangled attackers (2024) arxiv.org

    Generalises $f$-BB84 QPV to continuous-variable inputs and shows analogous security statements as for finite-dimensional inputs.

  5. Linear gate bounds against natural functions for position-verification (2024) arxiv.org

    Provides a robust linear lower bound on the number of quantum gates/measurements needed to attack the inner product function.

  6. Breaking simple quantum position verification protocols with little entanglement (2020) arxiv.org

    Considers the case when the input bases are related by different angles and shows dimension-dependent attacks depending on the angle. Notably, they show the angle $\pi/6$ (outside the Clifford hierarchy) can be attacked with a 6-dimensional resource state.
