Robust logarithmic entanglement lower bound for -routing
Kevin Bogner
In one-round -routing, Alice receives an -bit string and an unknown qubit, and Bob receives an -bit string . They exchange one simultaneous message each and cannot…

Security evaluation of quantum distance-bounding protocols via semidefinite programming
Kevin Bogner, Aysajan Abidin, Dave Singelee +1
Quantum distance-bounding (QDB) protocols let a verifier check that a prover is both genuine and physically nearby. During a timed fast phase of quantum communication, the verifier…

Security Framework for Quantum Distance-Bounding
Kevin Bogner, Aysajan Abidin, Dave Singelee +1
Distance-bounding (DB) protocols let a verifier upper-bound a prover's physical distance by timing rapid challenge-response exchanges. Quantum communication promises simpler DB pro…
