Composable simultaneous purification: when all communication scenarios reduce to spatial correlations
Matilde Baroni, Dominik Leichtle, Ivan Šupić +2
Bell non-locality is a powerful framework to distinguish classical, quantum and post-quantum resources, which relies on non-communicating players. Under which restriction can we ha…
Formalizing contextuality in sequential scenarios
Kim Vallée, Damian Markham
This paper provides a framework for characterizing sequential scenarios, allowing for the identification of contextuality given empirical data, and then provides precise operationa…
Robustly self-testing all maximally entangled states in every finite dimension
Uta Isabella Meyer, Ivan Šupić, Frédéric Grosshans +1
We establish a device-independent, noise-tolerant certification of maximally entangled states in every finite dimension . The core ingredient is a -input, -outcome Bell ex…
Translating Bell Non-Locality to Prepare-and-Measure Scenarios under Dimensional Constraints
Matilde Baroni, Eleni Diamanti, Damian Markham +1
Understanding the connections between different quantum information protocols has been proven fruitful for both theoretical insights and experimental applications. In this work, we…
Qudit Clauser-Horne-Shimony-Holt Inequality and Nonlocality from Wigner Negativity
Uta Isabella Meyer, Ivan Šupić, Damian Markham +1
Nonlocality is an essential concept that distinguishes quantum from classical models and has been extensively studied in systems of qubits. For higher-dimensional systems, certain…
Self-Testing Graph States Permitting Bounded Classical Communication
Uta Isabella Meyer, Ivan Šupić, Frédéric Grosshans +1
Self-testing identifies quantum states and correlations that exhibit nonlocality, distinguishing them, up to local transformations, from other quantum states. Due to their strong n…
Quantum bounds for compiled XOR games and -outcome CHSH games
Matilde Baroni, Quoc-Huy Vu, Boris Bourdoncle +3
Nonlocal games play a crucial role in quantum information theory and have numerous applications in certification and cryptographic protocols. Kalai et al. (STOC 2023) introduced a…
All graph state verification protocols are composably secure
Léo Colisson, Damian Markham, Raja Yehia
Graph state verification protocols allow multiple parties to share a graph state while checking that the state is honestly prepared, even in the presence of malicious parties. Sinc…
Corrected Bell and Noncontextuality Inequalities for Realistic Experiments
Kim Vallée, Pierre-Emmanuel Emeriau, Boris Bourdoncle +3
Contextuality is a feature of quantum correlations. It is crucial from a foundational perspective as a nonclassical phenomenon, and from an applied perspective as a resource for qu…
Decoherence Effects on the Non-locality of Symmetric States
A. Sohbi, I. Zaquine, E. Diamanti +1
The observation of the non-local properties of multipartite entangled states is of great importance for quantum information protocols. Such properties, however, are fragile and may…
Classicality of spin-coherent states via entanglement and distinguishability
D. Markham, V. Vedral
We investigate the classical nature of the spin coherent states. In addition to being minimum uncertainty states, as the size of the spin, S, increases, the classical nature is see…
