Observation of end-to-end pumping in a quasiperiodic Fibonacci-type photonic chain

Arnob Kumar Ghosh, Ang Chen, Ashraf El Hassan +3

Topological pumps offer a promising route to operate as connecting buses, supplying efficient and robust connectivity between non-neighboring elements in a network. Here, we invest…

Exponentially decreasing critical detection efficiency for any Bell inequality

Nikolai Miklin, Anubhav Chaturvedi, Mohamed Bourennane +2

We address the problem of closing the detection efficiency loophole in Bell experiments, which is crucial for real-world applications. Every Bell inequality has a critical detectio…

When More Light Means Less Quantum: Modeling Bell Inequality Degradation from Accidental Counts

Piotr Mironowicz, Mohamed Bourennane

We investigate how accidental counts, the detection events not originating from genuine entangled photon pairs, impact the observed violation of Bell inequalities in photonic exper…

Finite-size security analysis for quantum protocols: A Python framework using the Entropy Accumulation Theorem with graphical interface

Piotr Mironowicz, Mohamed Bourennane

We present a comprehensive software framework for the finite-size security analysis of quantum random number generation (QRNG) and quantum key distribution (QKD) protocols, based o…

How to avoid (apparent) signaling in Bell tests

Massimiliano Smania, Matthias Kleinmann, Adán Cabello +1

Bell tests have become a powerful tool for quantifying security, randomness, entanglement, and many other properties, as well as for investigating fundamental physical limits. In a…

Experimental implementation of dimension-dependent contextuality inequality

Emil HÃ¥kansson, Amelie Piveteau, Alban Seguinard +4

We present a derivation and experimental implementation of a dimension-dependent contextuality inequality to certify both the quantumness and dimensionality of a given system. Exis…
