ERA NANOSCI: NanoEngineered Diamond for Quantum Information Technology

该项目的主要长期目标是将单个原子放置在纳米结构的钻石中，以设计可扩展的量子逻辑元件。控制单个量子系统位置的能力是发展单原子器件的根本关键。在量子计算的情况下，也需要精确控制内部量子态。我们已经确定了金刚石中有希望的杂质原子，它们具有光学活性，即使在室温下也具有很长的相干时间。将实现对单个原子进行寻址的光学技术，以读出在单个原子自旋中编码的量子信息。第二个短期目标是为量子通信开发高效的基于金刚石的单光子源。最后，将单原子的精确掺杂技术与光学控制相结合，有可能远远超出量子信息和自旋电子学的标准范式。

The primary long-term objective of this project is to place single atoms in nanostructured diamond to engineer scalable quantum logic elements. The ability to control the position of individual quantum systems is the fundamental key for the development single atom devices. In the case of quantum computing, precise control of the internal quantum states is also required. We have identified promising impurity atoms in diamond that are optically active and have very long coherence times, even at room temperature. Optical technology for addressing individual atoms will be implemented for read-out of quantum information encoded in the spin of an individual atom. A secondary short-term objective is to develop efficient diamond-based single-photon sources for quantum communication. Finally, combining the technology of precise doping of single atoms with optical control has the potential to extend well beyond the standard paradigms of quantum information and spintronics.
