(Phys.org)—A lot of attention has been given to the differences between the quantum and classical worlds. For example,quantum entanglement, superposition, and teleportation are purely quantum phenomena with no classical counterparts. However,when it comes to certain areas of thermodynamics—specifically, thermal engines and refrigerators—quantum and classical systems so far appear to be nearly identical. It seems that the same thermodynamic laws that govern the engines in our vehicles may also accurately represent the tiniest quantum engines consisting of just a single particle.
