Quantum Physical Unclonable Function based on Chaotic Hamiltonians
Soham Ghosh, Holger Boche, Marc Geitz
Quantum Physical Unclonable Functions (QPUFs) are hardware-based cryptographic primitives with strong theoretical security. This security stems from their modeling as Haar-random u…
Entanglement-assisted Quantum Error Correcting Code Saturating The Classical Singleton Bound
Soham Ghosh, Evagoras Stylianou, Holger Boche
We introduce a construction for entanglement-assisted quantum error-correcting codes (EAQECCs) that saturates the classical Singleton bound with less shared entanglement than any k…
Entanglement-assisted authenticated BB84 protocol
Pol Julià Farré, Vladlen Galetsky, Soham Ghosh +2
In this work, we present a novel authenticated Quantum Key Distribution (QKD) protocol employing maximally entangled qubit pairs. In the absence of noise, we securely authenticate…
Optimal depth and a novel approach to variational quantum process tomography
Vladlen Galetsky, Pol Julià Farré, Soham Ghosh +2
In this work, we present two new methods for Variational Quantum Circuit (VQC) Process Tomography onto qubits systems: PT_VQC and U-VQSVD. Compared to the state of the art, PT_…
