Position-based quantum cryptography and catalytic computation (2016)

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

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

Practical position-based quantum cryptography (2015)

Considers the case where the two input bases are related by a unitary $U$

Single-qubit loss-tolerant quantum position verification protocol secure against entangled attackers (2023)

Tightly characterises the secure region of the protocol depending on the loss and error rates
