It is not a trivial task to answer whether a free fermion-based architecture for a quantum computer can efficiently execute basic gates such as the Fredking gate. We show that a set of free fermions can efficiently execute Fredkin gate.

由一组自由费米子执行弗雷德金门

回答用于量子计算机的基于自由费米子的架构是否可以有效地执行基本门（例如弗雷德金门）并非易事。我们表明一组自由费米子可以有效地执行弗雷德金门。
