NV centers are great magnetometers, but their amazing sensitivity is lost outside cryogenic environments. But what is lost can sometimes be found, and today's guests, Raffaele Santagati and Antonio Andres Gentile, have just discovered how to fix the situation.
We discuss: NV centers, Hamiltonian learning, quantum sensors and machine learning. Basically, all the good stuff.
