本文和下一篇文章分别计算了两个单通量量子系统的性质。第一个系统是一个量子管（一个单结干涉仪）与一个约瑟夫森门作为结。通过适当改变其临界电流，可以通过远小于Φo的小外部通量来控制量子稳态的切换。这个“参数量子管”可以作为单个量子逻辑系统的基本单元。该器件最奇妙的特性是，在一个逻辑步骤中的能量耗散（PτT因子）可以远远小于热能KBT，并且仅受量子效应的限制：Pτ2\simg102h。
In this paper and the following one, the properties of two systems operating with single flux quanta are calculated. The first system is a quantron (a one-junction interferometer) with a Josephson gate as a junction. By a proper change of its critical current in time, the switching of quantron stable states can be controlled by a small external flux much less than Φo. This "Parametric Quantron" can be used as the basic cell of a Single Quantum Logic System. The most wonderful property of this device is that the energy dissipation during one logical step (PτT factor) can be much less than the thermal energy KBT and is limited by quantum effects only: Pτ2\simg102h.
