ATYPIQUAL’s main objective is to unveil a room temperature quantum technology platform based on a novel generation of Atomically Precise graphene nanoRibbons (APRs) and demonstrate its feasibility through technologically relevant devices. By definition, quantum technologies exploit the peculiar quantum properties of matter such as superposition, tunneling, and entanglement to develop tools and devices with new, non-classical functionalities. However, derived using conventional top-down techniques, these technologies lack atomic precision and are much more sensitive to environmental disturbances as compared to the electrical current switching in transistors. As such, they often require ultra-low temperature operation and impose important constraints on their general applicability. This makes their manipulation and integration to chip-scale substrates a major challenge. ATYPIQUAL is a highly interdisciplinary project that proposes a radically different high-risk bottom-up approach that uniquely offers to naturally 'hard-wire' complex quantum states into atomically precise carbon nanostructures: APRs. They exhibit novel physical properties beyond graphene such as topological quantum phases and spin polarization, all tailorable by their topology and edge structure. However, the demonstration of these electronic properties requires atomic precision control that can only be achieved through recent advances in bottom-up synthesis. We shall exploit atomically precise bottom-up on-surface synthesis to develop these novel advanced APRs offering on-demand multi-functionalities while relying on a single graphene nanoribbon backbone. By developing the required material processing and device fabrication steps and demonstrating the first technologically relevant feasibility examples, ATYPIQUAL will set the stage for a new quantum technology platform for atomically tunable multifunctional devices with applications in next-generation electronics, photonics and spintronics.

ATYPIQUAL的主要目标是推出基于新一代原子精确石墨烯纳米带（APR）的室温量子技术平台，并通过技术相关设备证明其可行性。根据定义，量子技术利用物质特有的量子特性，如叠加、隧穿和纠缠，开发具有新的非经典功能的工具和设备。然而，使用传统的自上而下的技术，这些技术缺乏原子精度，并且与晶体管中的电流切换相比，对环境干扰更加敏感。因此，它们通常需要超低温操作，并对其普遍适用性施加重要限制。这使得它们的操作和集成到芯片级基板上成为一个重大挑战。ATYPIQUAL是一个高度跨学科的项目，提出了一种完全不同的高风险自下而上的方法，独特地提供了自然的“硬连线”复杂的量子态到原子精确的碳纳米结构：APR。它们表现出超越石墨烯的新物理性质，如拓扑量子相和自旋极化，所有这些都可以通过它们的拓扑结构和边缘结构进行调整。然而，这些电子特性的演示需要原子的精确控制，这只能通过自下而上合成的最新进展来实现。我们将利用原子级精确的自下而上的表面合成来开发这些新的先进的APR，提供按需的多功能性，同时依赖于单个石墨烯纳米骨架。通过开发所需的材料加工和设备制造步骤，并展示第一个技术相关的可行性示例，ATYPIQUAL将为原子可调多功能设备的新量子技术平台奠定基础，该平台可应用于下一代电子学，光子学和自旋电子学。
