正如“经典”信息技术建立在互联信息处理系统的基础上一样，量子信息技术（QIT）也必须这样做。这种系统的一个关键组成部分是“互连”，一种允许在不同的物理介质（例如半导体电子器件、单个原子、光纤中的光脉冲或微波场）之间传输信息的设备或过程。虽然互连在经典信息技术领域已经被很好地设计了几十年，但量子互连（QuIC）提出了特殊的挑战，因为它们必须允许脆弱的量子态在系统的不同物理部分或自由度之间转移。QIT平台的多样性（超导、原子、固态色心、光学等）这将形成一个“量子互联网”带来了额外的挑战。随着量子系统规模的扩大，量子互连瓶颈迫在眉睫，并成为QIT面临的巨大挑战。出于这些原因，NSF“量子互连”研讨会的参与者所代表的社区的立场是，加速QuIC研究对于国家量子科学和技术计划的持续发展至关重要。鉴于QIT平台、所用材料、应用程序和所需基础设施的多样性，需要一个融合的研究计划，包括学术界、工业界和国家实验室之间的合作伙伴关系。
Just as "classical" information technology rests on a foundation built of interconnected information-processing systems, quantum information technology (QIT) must do the same. A critical component of such systems is the "interconnect," a device or process that allows transfer of information between disparate physical media, for example, semiconductor electronics, individual atoms, light pulses in optical fiber, or microwave fields. While interconnects have been well engineered for decades in the realm of classical information technology, quantum interconnects (QuICs) present special challenges, as they must allow the transfer of fragile quantum states between different physical parts or degrees of freedom of the system. The diversity of QIT platforms (superconducting, atomic, solid-state color center, optical, etc.) that will form a "quantum internet" poses additional challenges. As quantum systems scale to larger size, the quantum interconnect bottleneck is imminent, and is emerging as a grand challenge for QIT. For these reasons, it is the position of the community represented by participants of the NSF workshop on "Quantum Interconnects" that accelerating QuIC research is crucial for sustained development of a national quantum science and technology program. Given the diversity of QIT platforms, materials used, applications, and infrastructure required, a convergent research program including partnership between academia, industry, and national laboratories is required.
