Over the years, researchers have developed several theories regarding the ‘quantum heat engine’, based on the ideas of Scovil and Schulz-DuBois, introducing proposals of thermodynamic cycles at the quantum scale. Recently, a team of researchers from the University of Waterloo has successfully shown a spin quantum heat engine in a laboratory setting. Researchers successfully performed a proof-of-principle quantum heat engine using a nuclear spin placed in a chloroform molecule and nuclear magnetic resonance methods. Researchers now hope to recognize ways to optimize the development of small quantum thermal machines in the future, proving their effectiveness in practical trials.
