Solid state electronic devices have transformed our lives over the past fifty years: the development of devices like the transistor, integrated circuits and magnetic hard disks have given us a revolution in computing power, portable electronics and the ability to store and handle vast amounts of data. Quantum technologies aim to harness the power of quantum physics to deliver a further revolution in areas such as computing, sensing and communication. The UK is currently making a major investment in the exploitation of quantum science research to deliver a range of quantum technologies - so far this investment has focused on platforms of photonics, cold atoms and trapped ions. The aim of our proposal, Quantum Engineering of Solid-State Technologies, or QUES2T, is to address the capability gap in in quantum solid-state technologies and ensure the UK is in a strong competitive position in some of the most high-impact and scalable quantum technologies. In QUES2T we focus on three solid-state platforms which are well-poised to make significant commercial impact: i) silicon nano-devices, ii) superconducting circuits and iii) diamond-based devices. Each of these materials have demonstrated outstanding properties: silicon can store quantum information for a record-breaking 3 hours, superconducting circuits have been used to make the most complex quantum devices to date, while diamond based magnetometer have a sensitivity to image individual proton spins in a second. We will exploit these properties to develop practical quantum technologies. Importantly, we do not consider these platforms in isolation. A key strength and unique feature of QUES2T is that it not only provides essential infrastructure in each of these three areas but that it brings together a team of people with expertise across these different platforms. This will allow exchange of cross-fertilisation of different disciplines through transfer of expertise and the accelerated development of hybrid technologies that combine the best properties of different materials, to make new detectors, memories, and processors. QUES2T will allow UK researchers and their collaborators to exploit the advantages of developing new quantum devices based on solid state technologies, including easier integration with existing conventional technologies (such as CMOS processors) and reduced timescales to market and manufacturing. The capital infrastructure of QUES2T will establish world-class fabrication capabilities to manufacture high-quality quantum device prototypes out of a range of materials. It will also enable the creation of low-temperature technology test-beds to test the prototypes and develop technology demonstrators. These test-beds will combine a number of essential features, enabling devices to be addressed optically using lasers, with microwave pulses, under low-noise electrical measurements, and all at a hundredth of a degree kelvin. Such systems will be unique UK.To deliver our vision, we have established strong links with academic and industrial partners to exchange the latest technology, expertise and materials. Examples are ultra low-phase noise signal generators with applications in fast high-fidelity qubit control or isotopically pure materials for quantum prototypes in Si and diamond. Industry users working on quantum technologies will be actively encouraged to access the QUES2T infrastructure, such as a state-of-the-art 100 keV electron beam writer to make devices with 10nm features. Many industry partners will also be end users of the technologies that will be developed through QUES2T. Early technologies include scanning probe devices enabling magnetic resonance imaging at the single molecule level and quantum current standards counting electrons one-by-one. On a longer timescale, a fault-tolerant and scalable Si or superconducting based quantum processor, would be form the basis of a new and disruptive industry in computing.

过去五十年来，固态电子设备改变了我们的生活：晶体管、集成电路和磁性硬盘等设备的发展给我们带来了计算能力、便携式电子产品以及存储和处理大量数据的能力方面的革命。量子技术旨在利用量子物理的力量在计算、传感和通信等领域带来进一步的革命。英国目前正在对量子科学研究的开发进行重大投资，以提供一系列量子技术——到目前为止，这项投资主要集中在光子学、冷原子和俘获离子平台上。我们的提案“固态技术量子工程”（QUES2T）的目的是解决量子固态技术的能力差距，并确保英国在一些最具影响力和可扩展的量子技术方面处于强有力的竞争地位。在 QUES2T 中，我们重点关注三个固态平台，这些平台有望产生重大商业影响：i) 硅纳米器件，ii) 超导电路和 iii) 金刚石基器件。这些材料都表现出了出色的特性：硅可以存储量子信息破纪录的 3 小时，超导电路已被用来制造迄今为止最复杂的量子设备，而基于金刚石的磁力计具有在一秒钟内对单个质子自旋进行成像的灵敏度。我们将利用这些特性来开发实用的量子技术。重要的是，我们不会孤立地考虑这些平台。 QUES2T 的一个关键优势和独特之处在于，它不仅在这三个领域中提供必要的基础设施，而且汇集了跨这些不同平台的专业知识团队。这将通过专业知识的转移和加速混合技术的开发来实现不同学科的交叉融合，这些技术结合了不同材料的最佳特性，以制造新的探测器、存储器和处理器。 QUES2T 将使英国研究人员及其合作者能够利用开发基于固态技术的新型量子器件的优势，包括更轻松地与现有传统技术（例如 CMOS 处理器）集成以及缩短上市和制造时间。 QUES2T 的资本基础设施将建立世界一流的制造能力，用各种材料制造高质量的量子器件原型。它还将有助于创建低温技术试验台来测试原型并开发技术演示器。这些测试台将结合许多基本功能，使设备能够使用激光、微波脉冲、低噪声电气测量以及百分之一开尔文度进行光学寻址。这样的系统将是英国独一无二的。为了实现我们的愿景，我们与学术和工业合作伙伴建立了牢固的联系，以交流最新的技术、专业知识和材料。例如，超低相位噪声信号发生器应用于快速高保真量子位控制或用于硅和金刚石量子原型的同位素纯材料。我们将积极鼓励从事量子技术的行业用户访问 QUES2T 基础设施，例如用于制造具有 10nm 功能的设备的最先进的 100 keV 电子束写入器。许多行业合作伙伴也将成为通过 QUES2T 开发的技术的最终用户。早期技术包括能够在单分子水平上进行磁共振成像的扫描探针装置和逐一计数电子的量子电流标准。从长远来看，容错且可扩展的硅或超导量子处理器将成为新的颠覆性计算行业的基础。
