介孔基质参数对量子计算的影响
Effect of matrix parameters on mesoporous matrix based quantum computation
摘要：
我们提出了一种量子计算的固态实现，它改进了以前提出的光驱动方案。我们的建议是基于垂直阵列的量子点嵌入在一个介孔材料，可以制造与目前的技术。我们研究了不同介孔基质进行量子计算的可行性。我们分析了哪些基质材料可以确保量子点的每一个单独的堆栈可以被认为是与整体的其余部分隔离的，这是我们方案的关键要求。对于所有具有可行结构参数的基质材料和GAN/AlN基量子点，都满足这一要求。我们还表明，一维系综大大提高性能，甚至CdSe/CdS为基础的量子点。
英文摘要：
We present a solid state implementation of quantum computation, which improves previously proposed optically driven schemes. Our proposal is based on vertical arrays of quantum dots embedded in a mesoporous material which can be fabricated with present technology. We study the feasibility of performing quantum computation with different mesoporous matrices. We analyse which matrix materials ensure that each individual stack of quantum dots can be considered isolated from the rest of the ensemble-a key requirement of our scheme. This requirement is satisfied for all matrix materials for feasible structure parameters and GaN/AlN based quantum dots. We also show that one dimensional ensembles substantially improve performances, even of CdSe/CdS based quantum dots.
