Certified randomness from quantum speed limits
Caroline L. Jones, Albert Aloy, Gerard Higgins +1
Quantum speed limits are usually regarded as fundamental restrictions, constraining the amount of computation that can be achieved within some given time and energy. Complementary…
Theory-independent monitoring of the decoherence of a superconducting qubit with generalized contextuality
Albert Aloy, Matteo Fadel, Thomas D. Galley +2
Characterizing the nonclassicality of quantum systems under minimal assumptions is an important challenge for quantum foundations and technology. Here we introduce a theory-indepen…
On the significance of Wigner's Friend in contexts beyond quantum foundations
Caroline L. Jones, Markus P. Mueller
There has been a surge of recent interest in the Wigner's Friend paradox, sparking several novel thought experiments and no-go theorems. The main narrative has been that Wigner's F…
Spin-bounded correlations: rotation boxes within and beyond quantum theory
Albert Aloy, Thomas D. Galley, Caroline L. Jones +2
How can detector click probabilities respond to spatial rotations around a fixed axis, in any possible physical theory? Here, we give a thorough mathematical analysis of this quest…
