Quantum computing is a rapidly emerging technology offering transformative changes to society as a whole by providing vast improvements in computational capability that will solve complex many-body problems that are currently intractable. It will potentially deliver advancements in diverse fields such as finance, climate change, infrastructure planning, drug discovery, secure communications and material science.Trapped-ion Quantum Computing (TIQC) systems are one of the most advanced and promising quantum computing platforms in which an oscillating electric field is used to confine ions which serve as the qubits used to encode quantum information. This approach offers a route towards scaling up the number of qubits and thereby delivering the increase in computing power that is ultimately desired, allowing the technology to emerge from small scale lab-based experimental environments to integrated user-friendly systems for everyday use. Laser sources are a key requirement in TIQC, performing essential system functions including ionisation, cooling, repumping and spectroscopy. Typically these different requirements are served by a wide range of laser sources, each with different wavelengths and performance requirements.The ADRENALIN project will develop a novel type of laser, a Photonic Crystal Surface Emitting Lasers (PCSEL) for use in QT applications. PCSELs employ photonic crystals to produce 2nd order out-of-plane diffraction and enable vertical, single-frequency emission. This novel device architecture provides excellent beam quality compared to other laser diodes and significantly reduces manufacturing costs. PCSELs can also be configured in 2D arrays with steerable individually addressable output, enabling different lattice sites to be addressed simultaneously. In addition these devices can be manufactured in most III-V semiconductors, allowing most of the wavelength range used in QT applications to be addressed.The many advantages of the PCSEL device will help facilitate scaling in next generation TIQC systems to accommodate larger numbers of qubits thereby enabling exponential increases in computational power and more widespread utilisation of the technology. The PCSEL will also help drive miniaturisation in QT applications -- this is important in TIQC but is also a key driver in the development of miniature atomic clocks for portable high-precision time-keeping, enabling a more widespread adoption of the technology and providing the potential to significantly advance improvements in transportation, defence and communication sectors. In both applications, PCSELs will ultimately displace incumbent light sources which typically rely on relatively bulky, expensive and complicated external cavity lasers and will become essential components in future QT systems.

量子计算是一项快速新兴的技术，它通过在计算能力方面提供了广泛的改进，从而为整个社会提供了变革性的变化，这将解决当前棘手的复杂多体问题。它可能会在财务，气候变化，基础设施计划，药物发现，安全通信和材料科学等各种领域的进步。被困的离子量子计算（TIQC）系统是最先进且最有前途的量子计算平台之一，在该平台中，将使用振荡电场作为旋转电场，以将其当作用于Qubits量化量化量化的量子的量化量。这种方法提供了扩大量子数量的途径，从而提供了最终所需的计算能力的增加，从而使该技术从基于小规模的实验室实验环境到集成的用户友好型系统供日常使用。激光源是TIQC的关键要求，执行基本系统功能，包括电离，冷却，降压和光谱法。通常，这些不同的需求由多种激光源满足，每个激光源具有不同的波长和性能要求。肾上腺素项目将开发一种新型的激光，这是一种用于QT应用中的光子晶体表面发射激光器（PCSEL）。 PCSEL采用光子晶体产生2阶的脱离平面衍射并实现垂直，单频发射。与其他激光二极管相比，这种新颖的设备架构可提供出色的光束质量，并大大降低了制造成本。 PCSEL也可以在2D数组中配置，并具有可进入的单独寻址输出，从而可以同时解决不同的晶格站点。此外，这些设备可以在大多数III-V半导体中生产，从而使QT应用程序中使用的大多数波长范围都可以解决。PCSEL设备的许多优势将有助于促进下一代TIQC系统的扩展，从而适应大量的Qubits，从而在计算能力和更广泛的技术方面实现了多大的增长。 PCSEL还将有助于推动QT应用程序中的小型化 - 这在TIQC中很重要，但也是开发微型原子钟的关键驱动力，用于便携式高精度时间保持，从而更加广泛地采用了该技术，并为运输，国防和交流部门提供了显着改善的潜力。在这两种应用中，PCSEL最终都将取代现有的光源，这些光源通常依赖于相对笨重，昂贵且复杂的外部空腔激光器，并将成为未来QT系统中必不可少的组件。
