论文摘要
我们提出了一个一位全加制品的建议，以基于三重量子点系统的量子可逆动力来处理经典信息。该设备通过重复执行弗雷德金门通过单个时间独立的哈密顿式的动力学实现。我们的建议使用现实的参数值，可以在当前可用的量子点体系结构上实现。我们将运营我们的全制定能源需求与众所周知的完全古典设备进行了比较，并认为我们的建议可能会提供更好的能源效率。我们的工作是通过连贯的量子动力学运行的节能信息技术的原理证明。
We present a proposal for a one-bit full-adder to process classical information based on the quantum reversible dynamics of a triple quantum dot system. The device works via the repeated execution of a Fredkin gate implemented through the dynamics of a single time-independent Hamiltonian. Our proposal uses realistic parameter values and could be implemented on currently available quantum dot architectures. We compare the estimated energy requirements for operating our full-adder with those of well-known fully classical devices, and argue that our proposal may provide a consistently better energy efficiency. Our work serves as a proof of principle for the development of energy-efficient information technologies operating through coherent quantum dynamics.
