量子点分子中的全光控相位门

All-optical controlled phase gate in quantum dot molecules

Li-Bo Chen, Wen Yang

摘要:

提出了一种利用绝热通道和空穴隧穿在量子点分子中实现的双量子比特光控相位门。我们的方案结合了当前一代垂直堆叠自组装InAs量子点和绝热通道的优点。仿真结果表明,该门的保真度超过0.98。

英文摘要:

We propose a two-qubit optically controlled phase gate in quantum dot molecules via adiabatic passage and hole tunneling. Our proposal combines the merits of the current generation of vertically stacked self-assembled InAs quantum dots and adiabatic passage. The simulation shows an implementation of the gate with a fidelity exceeding 0.98.
