Continuous-variable approximate unitary 2-design, with applications to unclonable encryption
Arpan Akash Ray, Boris Skoric
We introduce an -approximate unitary 2-design that is compatible with the structure of p- and q-quadratures in continuous-variable (CV) quantum systems. The design uni…
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…
Practical Unclonable Encryption with Continuous Variables
Arpan Akash Ray, Boris Škorić
We propose the first continuous-variable (CV) unclonable encryption scheme, extending the paradigm of quantum encryption of classical messages (QECM) to CV systems. In our construc…
Continuous-variable Quantum Position Verification secure against entangled attackers
Rene Allerstorfer, Llorenç Escolà-Farràs, 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…
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…
Security of a Continuous-Variable based Quantum Position Verification Protocol
Rene Allerstorfer, Llorenç Escolà-Farràs, Arpan Akash Ray +3
In this work we study quantum position verification with continuous-variable quantum states. In contrast to existing discrete protocols, we present and analyze a protocol that util…
