We can use heat to do work, but to do so we must inevitably make other alterations, e.g. letting heat flow from hot to cold and thereby bringing the system closer to equilibrium.

This two-qubit gate together with single-qubit rotations, is universal for quantum computation, i.e. any arbitrary unitary ...
