Random coding for long-range continuous-variable QKD
Arpan Akash Ray, Boris Skoric
Quantum Key Distribution (QKD) schemes are key exchange protocols based on the physical properties of quantum channels. They avoid the computational-hardness assumptions that under…

Continuous-Variable Quantum Key Distribution with key rates far above the PLOB bound
Arpan Akash Ray, Boris Skoric
Continuous-Variable Quantum Key Distribution (CVQKD) at large distances has such high noise levels that the error-correcting code must have very low rate. In this regime it becomes…

Continuous-variable Quantum Position Verification secure against entangled attackers
Rene Allerstorfer, Llorenç Escolà -Farrà s, Arpan Akash Ray +2
Motivated by the fact that coherent states may offer practical advantages it was recently shown that a continuous-variable (CV) quantum position verification (QPV) protocol using c…
