Practical position-based quantum cryptography (2015)

Perfect cheating is impossible for single-qubit position verification (2024)

Considers a generalisation where the input qubits are eigenstates of a $\mathbb{C}^2$ projector chosen uniformly at random. Shows that no finite-dimensional resource state can perfectly attack this protocol

Towards practical and error-robust quantum position verification (2021)

Defines a new protocol based on the SWAP test and studies it theoretically and practically

Security of a continuous-variable based quantum position verification protocol (2023)

Generalises the protocol to continuous variable inputs and shows security against unentangled attacks depending on loss and noise rates

Position-based quantum cryptography and catalytic computation (2016)

Chapter 5 independently generalises BB84 QPV to more input bases. Chapter 4 provides an efficient attack on the protocol based on interleaved unitaries
