Quantum Key Distribution with Entanglement-Swapped Photons from a Quantum Emitter
Quantum key distribution QKD is a fundamental functionality of quantum networks. Extending its range requires quantum repeaters, a technology still under development and not yet demonstrated in combination with quantum cryptographic protocols. Here, we address the elementary operation of a viable...
Classical Verifier Position Verification from Non-Local Games
Secure position verification certifies that a remote prover occupies a claimed location, a task that is provably impossible with classical resources alone against colluding adversaries. Most existing quantum position verification schemes require transmitting quantum states between verifiers and...
Computational Cryptography from Pseudoentanglement
The advent of pseudoentanglement and computational entanglement theory bootstrapped a wave of research at the intersection of computer science and information theory. In parallel, computational cryptography has undergone substantial development, prompted by the introduction of pseudorandom states...
Experimental Protocol Fingerprinting in Quantum Networks Via Physical Layer Side Channel Analysis
Quantum communication is a key enabler of next-generation networks, leveraging quantum entanglement to enable a new class of information exchange. While prior work has focused on the theoretical analysis of communication protocols, their exposure to physical layer side channel analysis remains...
Security of Quantum Conference Key Agreement with Two-Way Classical Communication
Quantum conference key agreement QCKA enables multiple users to establish a common secret key with information-theoretic security and is regarded as a key primitive for secure communication in future quantum networks. However, practical implementations of QCKA typically suffer from higher noise...
Full Network Nonlocality Based Security in Quantum Key Distribution
In the last decade research of quantum nonlocality has moved beyond the regime of standard Bell nonlocality to consider network-based experimental set-ups involving multiple independent sources. Notion of full network nonlocality has emerged as some truly network phenomena that cannot be realized...
QuaNTUM: A Modular Quantum Communication Testbed for Scalable Fiber and Satellite Integration
Secure communication is essential for modern society, from financial transactions to critical infrastructure. As classical encryption faces threats from advancing computational power, quantum communication provides a fundamentally secure alternative based on physical laws. We present QuaNTUM...
Enhanced Security in Quantum Token Protocols Using Hybrid Spin-Photon Interfaces
Quantum token protocols enable unforgeable quantum tokens promising unconditional security beyond classical cryptographic assumptions. We show here that the three stages of the Quantum token protocols involving the preparation, storage and verification can be made more secure when involving...
Cryptographic Fragility of Standard Quantum Repeater Protocols
The security of the proposed quantum Internet relies on repeater protocols designed under the assumption of stochastic, characterizable noise. We demonstrate that in adversarial environments this assumption induces performance vulnerabilities for computationally bounded repeater nodes. We show th...
On-Chip Semi-Device-Independent Quantum Random Number Generator Exploiting Contextuality
We present a semi-device-independent quantum random number generator QRNG based on the violation of a contextuality inequality, implemented by the integration of two silicon photonic chips. Our system combines a heralded single-photon source with a reconfigurable interferometric mesh to implement...
An Introductory Review of the Theory of Continuous-Variable Quantum Key Distribution: Fundamentals, Protocols, and Security
Continuous-variable quantum key distribution CV-QKD has emerged as a promising approach for secure quantum communication, offering advantages such as high key generation rates, compatibility with standard telecommunication infrastructure, and potential for integration on photonic chips. This revi...
Processing Entangled Links into Secure Cryptographic Keys
The following paper presents a holistic approach to the processing of entangled links within entanglement based quantum key distribution protocols, whose security relies on the Bell inequality. We investigate the interactions, and the collective impact, of the whole processing chain on the final...
