SPARQ(s) - Scalable, Precise, And Reliable positioning of color centers for Quantum computing and simulation

量子计算将给包括医学研究和药物发现、安全、密码学、金融和环境研究在内的众多技术带来革命性的变化。然而，事实证明，量子计算机(量子比特)的构建块制造起来速度慢、成本高且复杂，**Ionoptika的**Q-One仪器旨在使用户能够在钻石等基质中注入单一离子，并唯一地识别该离子是否已成功注入。少数欧洲研究实验室已经在研究Q-One，包括与Ionoptik密切合作的**萨里大学**。然而，一个限制因素是，离子注入的本质要求离子束必须非常精确地放置在离被注入的衬底很近的地方。这意味着只能使用一个离子束系统；根本不可能实现精确和准确的注入，需要将两个或更多的离子束放置在离表面等距离的位置。然而，选择一个离子束会带来妥协；每个离子束系统都以非常特定的方式工作，具有特定的物种。例如，Q-One上最常用的离子束系统是液态金属离子枪(LMIG)，它可以注入金、铒或锰等金属物种。然而，它不能植入氮气或氙气等气体物种，虽然可以通过额外的资金(即购买2台仪器)来克服这一折衷，但价格点为1 GB。对于大多数研究机构来说，这不是一个可行的解决方案。英国团队在这个项目中的目标是开发、测试和表征一种新型的双源系统(**金属*和气体离子柱魔术)**，旨在与Ionoptika的Q-One离子注入机一起使用。Magic将提供Q-One平台的终极技术升级。通过实现液态金属和等离子体离子源的无缝利用，Q-One将成为第一个商业上可用的单离子注入机系统，它将涵盖目前离子注入在学术和工业研究层面的全部技术应用。我们的德国合作者在材料开发、注入后处理和量子比特表征方面所开展的补充工作将提供独特的原理证明，坚定地确立单离子注入作为快速生产量子比特的方法的选择，并将Q-One作为这项具有国际意义的技术的选择工具。

Quantum-enabled Computing is set to revolutionise a myriad of technologies including medical research and drug discovery, security, cryptography, finance and environmental research. However the building blocks of Quantum Computers (Qubits) are proving slow, expensive and complex to manufacture,**Ionoptika's** Q-One instrument is designed to enable users to implant a single ion in a substrate such as diamond, and uniquely identify that the ion has successfully implanted. Work is underway already at a small number of European research laboratories on the Q-One, including the **University of Surrey** who collaborate closely with Ionoptika.One limiting factor however, is that the very nature of ion implantation requires that the ion beam must be placed very precisely and close to the substrate to be implanted. This means that only one ion beam system can be used; it is simply impossible to achieve precise and accurate implantation of 2 or more ion beams need to be positioned equidistant from the surface.However the choice of one ion beam brings about compromises; each ion beam system works in a very specific way with particular species. For example, the most commonly used ion beam system on a Q-One is a Liquid Metal Ion Gun(LMIG) which enables implantation of metal species such as Gold, Erbium or Manganese. It will not however enable implantation of gaseous species such as nitrogen or xenon.Whilst this compromise can be overcome with additional funding (i.e. the purchase of 2 instruments), at a price point of £1\. 3 million per instrument, this is not a viable solution for most research institutes.The goal of the UK team in this project is to to develop, test and characterize a novel dual-source system ( **Metal** **and Gas Ion Column - MaGIC)** intended for use with Ionoptika's Q-One Ion Implanter. MaGIC would offer the ultimate technological upgrade of the Q-One platform. By enabling the seamless utilisation of liquid metal and plasma ion sources the Q-One will become the first commercially available single ion implanter system which will cover the entirely spectrum of current technological applications of ion implantation both at academic and industrial research level.Complementary work carried out by our German collaborators in material development , post-implant treatment; and qubit characterization will provide a unique proof of principle, firmly establishing single ion implantation as the method of choice for fast Qubit production and the Q-One as the instrument of choice for this internationally significant technique.
