Experimental demonstration of finite-size general security via discrete-modulated CVQKD with real time postprocessing
Sven Bodenstedt, Carlos Pascual-García, Nil Canta i Pujol +5
Continuous-variable quantum key distribution (CVQKD) is compatible with telecommunication infrastructure, but implementing composable security with experimentally practical resourc…
Certifying quantum states without independence assumptions
Mariana Navarro, Leonardo Zambrano
Standard quantum verification and certification protocols often assume that experimental sources emit independent and identically distributed (i.i.d.) states. In realistic scenario…
Effective discrete-modulated continuous variable QKD under general attacks using dimension reduction
Mariana Navarro, Mateus Araújo, Antonio Acín +1
Continuous variable quantum key distribution via discrete modulations ensures information-theoretic security using standard telecom technologies, providing affordable and scalable…
Finite-size quantum key distribution rates from Rényi entropies using conic optimization
Mariana Navarro, Andrés González Lorente, Pablo V. Parellada +2
Finite-size general security proofs for quantum key distribution based on Rényi entropies have recently been introduced. These approaches are more flexible and provide tighter boun…
Sampling Groups of Pauli Operators to Enhance Direct Fidelity Estimation
Júlia Barberà-Rodríguez, Mariana Navarro, Leonardo Zambrano
Direct fidelity estimation is a protocol that estimates the fidelity between an experimental quantum state and a target pure state. By measuring the expectation values of Pauli ope…
Long-distance device-independent quantum key distribution using single-photon entanglement
Anna Steffinlongo, Mariana Navarro, Marina Cenni +3
Device-independent quantum key distribution (DIQKD) provides the strongest form of quantum security, as it allows two honest users to establish secure communication channels even w…
