近期,有关二硫化布法罗大学成功发现二硫化钨对量子数据的编码含义钨的新研讨可能为量子核算的开展翻开大门。在Nature Communications上宣布的一篇论文中,科学家称,他们能够操作这种超薄资料的电子特性来有用编码量子数据。

该研讨触及二硫化钨的能量谷,该论文的榜首作者,布法罗大学的物理学家郝曾将其描绘为“晶状固体中电子结构的部分能量极值”。在二硫化钨和二硒化钨中,两个能量谷的电子具有相反的自旋,即角动量方式。郝曾说,虽然这种特性关于创立量子位不是必需的,但能够供给对量子态鲁棒性的维护。


New research on two-dimensional tungsten disulfide (WS2) could open the door to advances in quantum computing. In a paper published in Nature Communications, scientists report that they can manipulate the electronic properties of this super-thin material in ways that could be useful for encoding 布法罗大学成功发现二硫化钨对量子数据的编码含义quantum data.

The study d豆荚行动队eals with WS2's energy valleys, which University at Buffalo physicist Hao Zeng, co-lead author of the paper, describes as "t布法罗大学成功发现二硫化钨对量子数据的编码含义he local energy extrema of the electronic structure in a crystalline solid." In both WS2 and WSe2, electrons populating the two energy valleys have opposite spins, a form of angular momentum. While this trait is not necessary for creating a qubit, it "provides certain protection of the quantum states, making them more robust," Zeng says.
