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…
Possible consequences for physics of the negative resolution of Tsirelson's problem
Adán Cabello, Marco Túlio Quintino, Matthias Kleinmann
In 2020, Ji et al. [arXiv:2001.04383 and Comm.~ACM 64}, 131 (2021)] provided a proof that the complexity classes and are equivalent. This result impli…
Certifying the activation of Bell nonlocality with finite data
Jonathan Steinberg, H. Chau Nguyen, Matthias Kleinmann
The activation of Bell nonlocality is a protocol that enables the violation of a Bell inequality from a system that initially did not allow for any such violation because the state…
Comparison of confidence regions for quantum state tomography
Jessica O. de Almeida, Matthias Kleinmann, Gael Sentís
The quantum state associated to an unknown experimental preparation procedure can be determined by performing quantum state tomography. If the statistical uncertainty in the data d…
