Monogamy of highly symmetric states (2023)

Quantum location verification in noisy channels (2010)

Studies QPV based on Bell states, GHZ states and entanglement swapping. Studies the effect of noise/decoherence

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

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

Loss-tolerant quantum secure positioning with weak laser sources (2016)

Studies a version of the protocol with separable inputs. Proves full loss tolerance and studies practical implementation based on decoy states

Insecurity of position-based quantum cryptography protocols against entanglement attacks (2011)

Proves insecurity of QPV protocols that were previously claimed secure and studies general principle underlying entanglement attacks. Studies variations of QPV protocols based on Bell/GHZ states and shows that using eigenstates other than Pauli $X$, $Y$, $Z$ leads to protocols that need >1 EPR pair to be attacked
