Holographic scattering requires a connected entanglement wedge (2020)
Furthers the connection between QPV and holography and estimates the mutual information between the relevant boundary regions. Results based on the conjecture could yield efficient attacks on all QPV protocols due to the results in this paper.

Quantum tasks in holography (2019) doi.org
Connects QPV to the AdS/CFT conjecture by noting that a QPV protocol in the bulk must have an equivalent protocol in the boundary. The boundary implementation turns out to be a valid attack on the bulk QPV protocol, implementing it non-locally.

Security of position-based quantum cryptography limits Hamiltonian simulation via holography (2024) doi.org
Connects QPV to Hamiltonian simulation. Shows that if a superlinear lower bound can be shown for QPV attacks, then there are new fundamental lower bounds for resources required for one Hamiltonian to simulate another.

Insecurity of position-based quantum cryptography protocols against entanglement attacks (2011) doi.org
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…

Location-dependent communications using quantum entanglement (2010) doi.org
Introduces QPV in the academic literature, but incorrectly claims unconditional security. Studies QPV based on Bell states.

Holography as a resource for non-local quantum computation (2022) arxiv.org
Discusses and fills a loophole in the paper one above. Costructs an attacked based on simulating a holographic CFT and argues that, based on some assumptions, any polynomially complex unitary can be efficiently attacked.

Introduces a rooster of different QPV protocols like BB84 QPV, $f$-routing, $f$-BB84 QPV and variations of them. Mentions entanglement-based attacks on some of them.
