Rafael Wagner#Coherence and #Contextuality fuel advantages in quantum information. It is crucial to #certify the presence of these in current #QuantumDevices.
In our #New_paper out on #Science_Advances
✅ We certify/benchmark their presence,
✅ We demonstrate that contextuality provides a quantum advantage for an information task,
✅ We benchmark coherence achieved only by using a major part of the device,
✅ The device is fabricated with state-of-the-art laser writing techniques
