Private training in quantum machine learning
Tigran Sedrakyan, Frédéric Grosshans, Elham Kashefi
With the emergence of machine learning (ML) models trained on large datasets containing potentially sensitive data, a major question in AI safety is how to make learning private wi…
A unified framework for Bell inequalities from continuous-variable contextuality
Carlos Ernesto Lopetegui-González, Gaël Massé, Enky Oudot +6
Although the original EPR paradox was formulated in terms of position and momentum, most studies of these phenomena have focused on measurement scenarios with only a discrete numbe…
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…
Multicopy quantum state teleportation with application to storage and retrieval of quantum programs
Frédéric Grosshans, Michał Horodecki, Mio Murao +4
This work considers a teleportation task for Alice and Bob in a scenario where Bob cannot perform corrections. In particular, we analyse the task of \textit{multicopy state telepor…
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…
Entanglement Swapping in Orbit: a Satellite Quantum Link Case Study
Paolo Fittipaldi, Kentaro Teramoto, Naphan Benchasattabuse +3
Satellite quantum communication is a promising way to build long distance quantum links, making it an essential complement to optical fiber for quantum internetworking beyond metro…
