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

doi.orgsite

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…
