Fault tolerance of quantum circuits with tensor networks and symplectic geometry
Soham Ghosh, Holger Boche, Andrew Tanggara
We develop an operator-algebraic framework for analyzing fault tolerance in quantum circuits and establish necessary and sufficient conditions for exact recovery of the ideal compu…
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_…
Existential Unforgeability in Quantum Authentication From Quantum Physical Unclonable Functions Based on Random von Neumann Measurement
Soham Ghosh, Vladlen Galetsky, Pol Juliá Farré +3
Physical Unclonable Functions (PUFs) leverage inherent, non-clonable physical randomness to generate unique input-output pairs, serving as secure fingerprints for cryptographic pro…
