Continuous-variable quantum position verification secure against entangled attackers
This work develops a continuous-variable quantum position verification protocol using coherent states and $n$-bit classical strings, which are practical to implement in laboratories. The protocol is proven secure against attackers with fewer than $c\phantom{\rule{0}{0ex}}n$ preshared entangled qubits, even under some attenuation, excess noise, and slow quantum signal transmission.
