门控双量子点的三电子结构是量子信息处理的一个很有前途的量子比特。我提出了一个两量子比特纠缠门使用脉冲门控操作程序。高保真纠缠操作的要求相当于已成功实现的脉冲选通单量子位操作的要求。这个双量子比特门完成了三电子双点量子比特的全脉冲门控操作的通用集合，并为实现量子计算的可扩展设置铺平了道路。
The three-electron configuration of gate-defined double quantum dots encodes a promising qubit for quantum information processing. I propose a two-qubit entangling gate using a pulse-gated manipulation procedure. The requirements for high-fidelity entangling operations are equivalent to the requirements for the pulse-gated single-qubit manipulations that have been successfully realized for Si QDs. This two-qubit gate completes the universal set of all-pulse-gated operations for the three-electron double-dot qubit and paves the way for a scalable setup to achieve quantum computation.
