Indian physicists first to measure quantum measure above one

Scientists at Bengaluru's Raman Research Institute have experimentally verified Rafael Sorkin's Quantum Measure Theory, showing that the quantum analogue of probability can exceed one. The measured value of 1.17 matched the theoretical prediction of 1.18. The work was published in the journal Quantum.
