项目摘要

Our society relies on secure communication, powerful computers and precise sensors. Basic science has shown that huge improvements in these capabilities are possible if we can utilise many single quantum objects working in concert. We can then see how to store and process huge amounts of information in a fully secure way and how to make exquisitely sensitive measurements of fields and forces. Specific types of quanta - photons, electrons, phonons - already bring new specific functions, but to realise the full promise of quantum technologies, it will be necessary to interface these systems with each other in a way that is practical and scalable. This is the focus of our programme.ORQUID will explore the exciting new possibility of using single organic molecules as the interface between these three quanta so that they can work together as required. First, single molecules will interact with light in waveguides and cavities to generate and detect single photons, providing immediate impact in quantum photonics. Second, single molecules will detect single moving charges in nano-electronic circuits to provide quantum coherent information exchange between these charges and the external world. Third, molecules embedded in nanomechanical devices and two-dimensional materials will measure nanoscale forces and displacements, which are key to developing mechanical quantum systems and understanding nano-machinery. By developing these three interfaces on a common platform, we will create a versatile hybrid system. By allowing the user to draw simultaneously on the most sensitive quantum aspects of light, charge and sound, we anticipate that this hybrid will be a major advance in the technology of quantum devices.In the spirit of QuantERA, the ORQUID consortium will "explore collaborative advanced multidisciplinary science...with the potential to initiate or foster new lines of quantum technologies and help Europe grasp leadership early on in promising future technology areas." ORQUID aligns with a number of the target outcomes of QuantERA. (i) Quantum Communications. Our programme will deliver "Novel photonic sources for quantum information and quantum communication" - specifically a chip containing 8 molecules acting as fast sources of identical photons. We will also deliver "Coherent transduction of quantum states between different physical systems" by using molecules to convert quantum information from electrons to photons. Both these elements of ORQUID fall under the umbrella of "Integrated quantum photonics." (ii) Quantum Computing. Our photon sources will also contribute to "devices to realise multi-qubit algorithms", as will the use of single molecules to make a strong nonlinearity that can mediate a photon-photon interaction. (iii) Quantum Information Science. We will use molecules and quantum interference to demonstrate "Novel sources of non-classical states and methods to engineer such states." Finally, in (iv) Quantum Sensing, our use of molecules to sense displacement, fundamental forces, charge, and phase will fit well with the demands for "Development of detection schemes that are optimised with respect to extracting relevant information from physical systems" and "Implementation of micro- and nano- quantum sensors."

我们的社会依赖于安全的通信、强大的计算机和精确的传感器。基础科学已经表明，如果我们能够利用许多单个量子物体协同工作，这些能力的巨大改进是可能的。然后，我们可以看到如何以完全安全的方式存储和处理大量信息，以及如何对场和力进行精确敏感的测量。特定类型的量子--光子、电子、声子--已经带来了新的特定功能，但为了实现量子技术的全部前景，有必要以实用和可扩展的方式将这些系统相互连接起来。这是我们计划的重点。ORQUID将探索使用单个有机分子作为这三个量子之间的界面的令人兴奋的新可能性，以便它们可以根据需要一起工作。首先，单分子将与波导和腔中的光相互作用，以产生和检测单光子，从而在量子光子学中产生直接影响。第二，单分子将探测纳米电子电路中的单个运动电荷，以提供这些电荷与外部世界之间的量子相干信息交换。第三，嵌入纳米机械设备和二维材料中的分子将测量纳米级的力和位移，这是开发机械量子系统和理解纳米机械的关键。通过在一个通用平台上开发这三个接口，我们将创建一个多功能的混合系统。通过允许用户同时利用光、电荷和声音的最敏感的量子方面，我们预计这种混合体将成为量子设备技术的重大进步。本着QuantERA的精神，ORQUID联盟将“探索合作的先进多学科科学...它有可能启动或培育新的量子技术，并帮助欧洲在未来有前途的技术领域尽早掌握领导地位。“ORQUID与QuantERA的许多目标结果一致。(i)量子通信我们的计划将提供“量子信息和量子通信的新型光子源”-特别是一个包含8个分子的芯片，作为相同光子的快速源。我们还将通过使用分子将量子信息从电子转换为光子来实现“不同物理系统之间量子态的相干转换”。ORQUID的这两个元素都属于“集成量子光子学”的范畴。“㈡量子计算。我们的光子源也将有助于“实现多量子比特算法的设备”，因为使用单分子来产生强非线性，可以介导光子-光子相互作用。(iii)量子信息科学.我们将使用分子和量子干涉来展示“非经典状态的新来源和设计这种状态的方法。“最后，在（iv）量子传感中，我们使用分子来感知位移，基本力，电荷和相位将很好地满足“开发检测方案，优化从物理系统中提取相关信息”和“实现微米和纳米量子传感器”的需求。"
