Of course, people spend the most time and resources trying to develop quantum computers, but there’s also advancements in things like the quantum internet, quantum cryptography, and yes, quantum AI. But since their introduction in 2012 , scientists have yet to convincingly establish the technology’s “quantum advantage”—does a quantum battery really surpass the function and capability of regular, old classical batteries? And now, a new study shows the first evidence of quantum advantage in this new type of battery. “The key ingredient enabling the quantum advantage is an anharmonic interaction between the two oscillators during the charging process.
