量子点阵列中通过条件单电子转移实现电荷量子比特纠缠

Charge qubit entanglement via conditional single-electron transfer in an array of quantum dots

A. V. Tsukanov

摘要:

我们提出了一种新的方案,通过辅助量子点结构中的顺序电子转移来产生基于量子点的电荷量子比特之间的纠缠,该结构的输运性质由量子比特态决定。传输协议需要利用与适当的电压门模式相结合的谐振光脉冲。作为一个例子,说明了该方案的应用,我们研究了九量子位的肖尔码状态的准备连同错误伴随式测量。

英文摘要:

We propose a novel scheme to generate entanglement among quantum-dot-based charge qubits via sequential electron transfer in an auxiliary quantum dot structure whose transport properties are conditioned by qubit states. The transfer protocol requires the utilization of resonant optical pulses combined with an appropriate voltage gate pattern. As an example illustrating the application of this scheme, we examine the nine-qubit Shor code state preparation together with the error syndrome measurement.
