[标题]:Szilard engine reversibility as quantum gate function

[作者]:F. Matthew Mihelic;

[文摘]:A quantum gate is a logically and thermodynamically reversible situation that effects a unitary transformation ofqubits of superimposed information, and essentially constitutes a situation for a reversible quantum decision. Aquantum decision is a symmetry break, and the effect of the function of a Szilard engine is a symmetry break. Aquantum gate is a situation in which a reversible quantum decision can be made, and so if a logically andthermodynamically reversible Szilard engine can be theoretically constructed then it would function as a quantumgate. While the traditionally theorized Szilard engine is not thermodynamically reversible, if one of the boundingwalls of a Szilard engine were to be constructed out of the physical information by which it functions in such amanner as to make that information available to both sides of the wall simultaneously, then such a Szilard enginewould be both logically and thermodynamically reversible, and thus capable of function as a quantum gate. Atheoretical model of the special case of a reversible Szilard engine functioning as a quantum gate is presented anddiscussed, and since a quantum decision is made when the shutter of a Szilard engine closes, the coherence of linkedreversible Szilard engines should be considered as a state during which all of the shutters of linked Szilard enginesare open simultaneously.
