Algorithmic Cooling and Scalable NMR Quantum Computers

I introduced an algorithmic procedure for cooling nuclear spins, referred to as Algorithmic Cooling, where the bulk polarization of a target set of nuclear spins can be increased (hence these spins are “cooled”) without having to cool the temperature of the bath itself. A number of international groups of chemists and physicists have implemented Algorithmic Cooling in their labs and shown its practicability. The related paper was published in the Proceedings of the National Academy of Sciences (PNAS).
