Claim:
A method for decreasing entropy of a quantum system of at least two subsystems, a first subsystem comprising computation elements which are elements with a first relaxation time and a second subsystem comprising reset elements which are elements with a second relaxation time, the second relaxation time being shorter than the first relaxation time, characterized by a relaxation time ratio defined as the ratio between the relaxation time of the computation elements and the relaxation time of the reset elements, the method comprising: adiabatically manipulating the entropy of the elements in the system, by way of entropy compression, entropy transfer or both, so as to decrease the entropy of at least some computation elements, and to increase the entropy of at least some reset elements, so that the entropy of the subgroup of reset elements is overall increased; and waiting for a time sufficiently longer than the relaxation time of the reset elements, and sufficiently shorter than the relaxation time of the computation elements for the total entropy of the subgroup of reset elements to decrease, wherein the step of adiabatically manipulating the entropy of the elements in the system and the step of waiting are carried out at least once, and wherein in at least one occurrence of the step of adiabatically manipulating the entropy, adiabatic manipulation is carried out on predetermined elements in the system, by way of entropy compression, entropy transfer or both, so as to decrease the entropy of at least some predetermined computation elements, and to increase the entropy of at least some predetermined reset elements, so that the entropy of the subgroup of reset elements is overall increased.
