石墨烯量子计算门的圆片级制备及室温实验

Wafer-scale fabrication and room-temperature experiments on graphene-based gates for quantum computation

Mircea Dragoman, Adrian Dinescu, Daniela Dragoman

摘要:

我们已经制造了适合在室温下实现单量子位量子门和改进的Deutsch-Jozsa算法的基于石墨烯的晶圆级配置。我们的测量证实了载流子通过这两种类型的器件传播的(准)弹道性质,这两种类型的器件的尺寸小于石墨烯中的室温平均自由程。因此,发现两种基于石墨烯的配置都适合于量子计算。这些结果对于展示基于石墨烯的小型化室温量子计算机是令人鼓舞的。

英文摘要:

We have fabricated at wafer scale graphene-based configurations suitable for implementing at room temperature one-qubit quantum gates and a modified Deutsch-Jozsa algorithm. Our measurements confirmed the (quasi-)ballistic nature of charge carrier propagation through both types of devices, which have dimensions smaller than the room-temperature mean-free-path in graphene. As such, both graphene-based configurations were found to be suitable for quantum computation. These results are encouraging for demonstrating a miniaturized, room-temperature quantum computer based on graphene.
