论文摘要

第一代商用量子计算机的开发分别基于超导量子和捕获的离子。其他技术,例如半导体量子点,中性离子和光子原则上可以为在中期获得可比的结果提供替代方案。鉴于创建通用量子计算机,评估其中一个或多个可以更有效地解决数百万量子位的可扩展性是否有效。我们回顾了一种全电动硅自旋量子置量置量值,即双量子点混合量子置量置量置量置量置量量子,这是一种量子技术,它依赖于一侧的固体理论基础,以及另一侧的纳米尺度设备的大量制造技术。

The development of the first generation of commercial quantum computers is based on superconductive qubits and trapped ions respectively. Other technologies such as semiconductor quantum dots, neutral ions and photons could in principle provide an alternative to achieve comparable results in the medium term. It is relevant to evaluate if one or more of them is potentially more effective to address scalability to millions of qubits in the long term, in view of creating a universal quantum computer. We review an all-electrical silicon spin qubit, that is the double quantum dot hybrid qubit, a quantum technology which relies on both solid theoretical grounding on one side, and massive fabrication technology of nanometric scale devices by the existing silicon supply chain on the other.
