The potential of quantum technology is fueling intense research worldwide. In 2019 the world observed a 53-qubit standalone quantum computer, eclipsing the computing power of the world's top supercomputer. Yet there remains a chasm between today's state-of-the-art capabilities, across dozens of physical platforms, and useful quantum computation. Networks of quantum computers unleash exponentially more capacity than the sum of their parts, and given expected environmental constraints, will be easier to build than monolithic quantum supercomputers. Eventually, quantum computers will be networked over global quantum telecommunication fibre optics, but there is no consensus on the quantum hardware interface that will unlock this ambitious objective. Rather, there is a fierce effort underway to prototype an ideal quantum interface between long-lived material-based qubits suitable for quantum computing, and telecommunications-band photons suitable for quantum networking. The world's foremost computing and telecommunications technologies are silicon-based, yet it was widely assumed that silicon does not have the requisite quantum interfaces necessary to make an all-silicon quantum internet. Dr. Simmons' recent work disproved this notion by producing and characterizing a silicon matter-telecom photon interface of the highest quality. Next, her team will deploy these matter-photon interfaces into real quantum devices and prove that they can underpin the quantum computation and communication technologies of the future.Specific objectives are to: 1) establish and improve the fidelity of single-qubit operations beyond quantum error-correction thresholds; 2) develop and demonstrate working multi-qubit entangling operations through the photonic interactions that these spin-photon interfaces provide; and 3) pursue new opportunities in the unexplored space of silicon colour centres for quantum information networks.A quantum internet will offer revolutionary capabilities that are otherwise impossible. The spectrum of future applications is likely beyond our current collective imaginations. Dr. Simmons' CRC research program will allow her to train future quantum leaders, build on her achievements, collaborations and infrastructure, and leverage a rare first-mover global competitive advantage and decades of silicon manufacturing R&D. If successful, this work may lead to a broad coalescence of research efforts toward a common quantum hardware dominant design.

量子技术的潜力正在推动全球范围内的紧张研究。2019年，世界观察到了一台53量子比特的独立量子计算机，使世界顶级超级计算机的计算能力黯然失色。然而，在今天跨越数十个物理平台的最先进的能力和有用的量子计算之间仍然存在鸿沟。量子计算机网络释放的容量比其组成部分的总和要大得多，而且考虑到预期的环境限制，将比单片量子超级计算机更容易构建。最终，量子计算机将通过全球量子电信光纤联网，但对于开启这一雄心勃勃的目标的量子硬件接口，各方尚未达成共识。相反，目前正在进行激烈的努力，以期在适合量子计算的长寿命材料量子比特和适合量子网络的电信波段光子之间建立理想的量子接口。世界上最先进的计算和电信技术是基于硅的，然而人们普遍认为硅没有制造全硅量子互联网所必需的量子接口。西蒙斯博士最近的工作通过制造和描述最高质量的硅物质-电信光子界面，驳斥了这一观点。接下来，她的团队将把这些物质-光子接口部署到真实的量子设备中，并证明它们可以支撑未来的量子计算和通信技术。具体目标是：1)建立和提高超出量子纠错阈值的单量子比特操作的保真度；2)通过这些自旋-光子接口提供的光子相互作用开发和演示工作中的多量子比特纠缠操作；以及3)在尚未探索的硅颜色中心空间中为量子信息网络寻求新的机会。量子互联网将提供否则不可能的革命性能力。未来的应用范围可能超出了我们目前的集体想象。西蒙斯博士的CRC研究项目将使她能够培训未来的量子领导者，在她的成就、合作和基础设施的基础上再接再厉，并利用难得的先发制人的全球竞争优势和数十年的硅制造研发。如果成功，这项工作可能会导致研究努力的广泛结合，朝着共同的量子硬件主导设计迈进。
