Abstract We report on the experimental quantification of the contribution to non-equilibrium entropy production stemming from the quantum coherence content in the initial state of a qubit exposed to both coherent driving and dissipation. Our experimental demonstration builds on the exquisite experimental control of the spin state of a nitrogen-vacancy defect in diamond and is underpin... https://www.getpureroutine.com/quick-grab-poise-pads-overnght-bulk-16-supply-mega-offer/
