Self-testing the toric code against classical communication
Gustavo Fróes, Amanda Wei, Carlos de Gois +2
Device-independent self-testing certifies a multipartite quantum state from the correlations it produces alone, without assumptions on the inner workings of the devices. Most exist…
Quantum communication and Bell nonlocality require infinite classical communication to simulate
Carlos de Gois, Thyago S. R. Santos, Carlos Vieira
A quantum system of any fixed dimension can be prepared in a continuum of states, yet it cannot be used to transmit an unlimited amount of classical information. Similarly, the cor…
Distributed Quantum Algorithms Cannot Color Cycles with Probability 1
Xavier Coiteux-Roy, Maxime Flin, Carlos de Gois +3
We prove that any distributed quantum algorithm that finds a -coloring with probability in a cycle of anonymous identical computers has to be global, that is, it needs $Ω(n)…
Generalized Mermin Inequalities for Benchmarking Large-Scale GHZ States
Jianbin Cai, Junxiang Huang, Fynn Otto +15
Multipartite Bell tests provide a correlation-only route to benchmarking quantum processors, but their application at large scales is hindered by the rapid decay of many-body corre…
Optimal Overlapping Tomography
Kiara Hansenne, Rui Qu, Lisa T. Weinbrenner +7
Characterising large-scale quantum systems is central to fundamental physics and essential for applications of quantum technologies. While a full characterisation requires exponent…
User-friendly confidence regions for quantum state tomography
Carlos de Gois, Matthias Kleinmann
Quantum state tomography is the standard technique for reconstructing a quantum state from experimental data. In the regime of finite statistics, experimental data cannot give perf…
Complete hierarchy for high-dimensional steering certification
Carlos de Gois, Martin Plávala, René Schwonnek +1
High-dimensional quantum steering can be seen as a test for the dimensionality of entanglement, where the devices at one side are not characterized. As such, it is an important com…
Uncertainty relations from graph theory
Carlos de Gois, Kiara Hansenne, Otfried Gühne
Quantum measurements are inherently probabilistic and quantum theory often forbids to precisely predict the outcomes of simultaneous measurements. This phenomenon is captured and q…
Interplays between classical and quantum entanglement-assisted communication scenarios
Carlos Vieira, Carlos de Gois, Lucas Pollyceno +1
Prepare-and-measure scenarios, in their many forms, can be seen as the basic building blocks of communication tasks. As such, they can be used to analyze a diversity of classical a…
