Scientists Measure Single Quantum of Heat

Experimental proof of predictive law of physics could help engineers better manage heat in microprocessors Photo: IBM Research IBM researchers have established experimental proof of a previously difficult-to-prove law of physics, and in so doing may have pointed to a way to overcome many of the heat management issues faced in today’s electronics. Researchers at(…)
