Today's internet, built upon the laws of classical physics, continues to revolutionize our lives. A quantum internet, based upon the intriguing and richer laws governing quantum bits (qubits), will offer additional revolutionary capabilities which are otherwise impossible to achieve. Networked quantum computers will teleport information; perform crucial computational tasks exponentially faster than the world's top supercomputers; generate provably impenetrable cryptography and provably secure cloud computation; and support the simulation of nature (drugs, materials) with a realism that simply cannot be approximated by any other means. Networks of quantum computers unleash exponentially more combined capacity than the sum of their parts, and given expected environmental constraints, will likely be far easier to build than monolithic quantum supercomputers. Given the nascent state of the field, the full spectrum of future applications of quantum technologies likely lies outside our current collective imaginations. The potential of this sector is fueling intense and accelerating research worldwide. Last year the world observed a 53-qubit standalone quantum computer eclipsing the computing power of the world's top supercomputer! Yet even though it is widely assumed that, eventually, quantum computers will be networked over global quantum telecommunication channels, there is no consensus around the quantum hardware interface which will unlock this ambitious objective. Quite the opposite: there is a fierce and growing worldwide search underway to prototype an ideal quantum interface between long-lived material-based qubits suitable for high performance quantum computing, and telecommunications photons suitable for quantum networking. Many imperfect interfaces, often in exotic materials and at the wrong wavelengths, have been thoroughly studied in the pursuit of this visionary aim. Despite the fact that silicon is the basis of both the world's foremost computing and telecommunications technologies, it was widely assumed that silicon did not have the requisite quantum interfaces necessary to make the dream of an all-silicon quantum internet a reality. Excitingly, our very recent work resoundingly disproved this notion: we have produced and characterized a silicon matter-telecom photon interface of the highest quality. The next steps are clear: we must deploy these matter-photon interfaces into real quantum devices and prove beyond all doubt that they can underpin the quantum computation and communication technologies of the near future. This grant will allow us to build on our achievements, collaborations, and world-class infrastructure, and leverage an exceedingly rare first-mover global competitive advantage as well as decades of silicon manufacturing R&D. It will support, train and produce future quantum leaders. If we are successful, we anticipate this work will lead to a broad coalescence of research efforts towards a quantum dominant design.

今天的互联网建立在古典物理法则的基础上，继续彻底改变我们的生活。量子互联网基于关于量子位（Qubits）的有趣和更丰富的法律，将提供其他革命性的功能，否则无法实现。网络量子计算机将传送信息；与世界顶级超级计算机相比，执行至关重要的计算任务；生成适当无法穿透的密码学并可能安全的云计算；并以一种现实主义的方式来支持自然的模拟（药物，材料），而这种现实主义根本无法通过任何其他方式近似。量子计算机的网络除非指数比其零件的总和更高，并且给出了预期的环境限制，否则构建可能比单片量子超级计算机更容易构建。鉴于该领域的新生状态，量子技术的未来应用潜在的全部应用在我们当前的集体想象之外。该行业的潜力在全球范围内加剧了激烈而加速的研究。去年，全世界观察到了53 Qubit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，即使广泛认为最终将通过全局量子电信通道进行联网，但量子硬件界面周围尚无共识，这将解锁这个雄心勃勃的目标。恰恰相反：正在进行猛烈且不断增长的全球搜索搜索原型，用于原型的理想量子界面，基于长期材料的量子计算与适用于量子网络的电信照片之间的理想量子接口。许多不完美的接口，通常是在异国情调的材料中，并且在错误的波长中，在追求这个有远见的目标方面已被彻底研究。尽管硅是世界上最重要的计算和电信技术的基础，但人们普遍认为，硅没有所需的量子接口来实现全硅量子互联网的梦想。令人兴奋的是，我们最近的工作令人反感，这一概念是：我们制作并表征了最高质量的硅物质 - 特征光子光子界面。接下来的步骤是明确的：我们必须将这些物质 - 光子接口部署到真实的量子设备中，并毫无疑问地证明它们可以支撑不久的将来的量子计算和通信技术。这笔赠款将使我们能够建立我们的成就，合作和世界一流的基础设施，并利用极为罕见的全球竞争优势以及数十年的硅制造R＆D。它将支持，培训和培养未来的量子领导者。如果我们成功，我们预计这项工作将导致广泛的研究努力与量子主导设计相结合。
