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…
A Review of the Applications of Quantum Machine Learning in Optical Communication Systems
Ark Modi, Alonso Viladomat Jasso, Roberto Ferrara +4
In the context of optical signal processing, quantum and quantum-inspired machine learning algorithms have massive potential for deployment. One of the applications is in error cor…
Quantum and Quantum-Inspired Stereographic K Nearest-Neighbour Clustering
Alonso Viladomat Jasso, Ark Modi, Roberto Ferrara +4
Nearest-neighbour clustering is a simple yet powerful machine learning algorithm that finds natural application in the decoding of signals in classical optical-fibre communication…
Testing of Hybrid Quantum-Classical K-Means for Nonlinear Noise Mitigation
Ark Modi, Alonso Viladomat Jasso, Roberto Ferrara +4
Nearest-neighbour clustering is a powerful set of heuristic algorithms that find natural application in the decoding of signals transmitted using the M-Quadrature Amplitude Modulat…
Comparison of Quantum PUF models
Vladlen Galetsky, Soham Ghosh, Christian Deppe +1
Physical unclonable functions (PUFs) are hardware structures in a physical system (e.g. semiconductor, crystals etc.) that are used to enable unique identification of the semicondu…
Integrating Quantum Simulation for Quantum-Enhanced Classical Network Emulation
Stephen DiAdamo, Janis Nötzel, Simon Sekavčnik +5
We describe a method of investigating the near-term potential of quantum communication technology for communication networks from the perspective of current networks. For this, we…
Key Assistance, Key Agreement, and Layered Secrecy for Bosonic Broadcast Channels
Uzi Pereg, Roberto Ferrara, Matthieu R. Bloch
Secret-sharing building blocks based on quantum broadcast communication are studied. The confidential capacity region of the pure-loss bosonic broadcast channel is determined, both…
Upper bounds on device-independent quantum key distribution
Matthias Christandl, Roberto Ferrara, Karol Horodecki
Quantum key distribution (QKD) is a method that distributes a secret key to a sender and a receiver by the transmission of quantum particles (e.g. photons). Device-independent quan…
Semantic Security for Quantum Wiretap Channels
Holger Boche, Minglai Cai, Christian Deppe +2
We consider the problem of semantic security via classical-quantum and quantum wiretap channels and use explicit constructions to transform a non-secure code into a semantically se…
Random private quantum states
Matthias Christandl, Roberto Ferrara, Cécilia Lancien
The study of properties of randomly chosen quantum states has in recent years led to many insights into quantum entanglement. In this work, we study private quantum states from thi…
Private states, quantum data hiding and the swapping of perfect secrecy
Matthias Christandl, Roberto Ferrara
We derive a formal connection between quantum data hiding and quantum privacy, confirming the intuition behind the construction of bound entangled states from which secret bits can…
