Testing on a superconducting qubit, they demonstrated decoherence by modeling the system as a general probabilistic theory. The system initially exhibited nonclassical behavior through generalized contextuality but lost this property over time as its state space contracted. The method also revealed non-Markovian evolution at late times, extending theory-independent tomography to time-evolving systems and enabling experimental monitoring of quantum phenomena without quantum theory assumptions. ## Full article daily.dev links to this article rather than hosting it.
