Recent efforts have demonstrated remarkable interconnects between solid-state qubits, atomic qubits, quantum sensing platforms, and solid-state ensembles. This not only provides for the next-generation of scalable compact quantum microprocessors, but also lays the foundation towards a transformative interconnected quantum network for quantum state transfer, sensing, computation, and communications. Advancing from the recent quantum intra-chip interconnects and processors demonstrated by the community, this team leads and advances the interdisciplinary frontier for quantum communications and interconnects – that of distributed entanglement and interconnected quantum networks. This is enabled by the team’s experimental contributions in high-dimensional time-frequency qubits for quantum communications, spin-photon readout of rare-earth ion-based quantum memories towards repeaters in network links, unique error correction algorithms and coding, and fundamental theoretical bounds and numerical computations. The interdisciplinary effort spans across Applied Physics, Chemistry, Electrical & Computer Engineering, Materials Science, Mathematics, and Physics. Working together with our industry and national laboratory colleagues, this team effort allows the examination of interconnected quantum network performance parameters, even in the presence of non-idealities. This QuIC-TAQS team studies three synergistic Thrusts to establish the cross-foundations towards a chip-scalable Interconnected Quantum Network. In Thrust I, the QuIC-TAQS team examines high-dimensional high-rate quantum photonic transmitters with integrated chip measurements. This includes a 8192-Hilbert space dimensionality in a high-rate link encoding, along with Bell state measurements and low-jitter detection. In Thrust II, the QuIC-TAQS team examines high-fidelity high-efficiency chip-scale quantum memories, in joint measurements between UCLA and Caltech. This is based on solid-state erbium-ions with dynamical control towards network repeaters. Unique protocols and coherence time improvements will be studied. In Thrust III, the QuIC-TAQS team examines robust quantum links, including coding and architecture, to establish a quantum network testbed at UCLA. Supporting the measurements, protocol improvements and numerical simulations of the network performance will be examined. The examined QuIC-TAQS Thrusts spans across integrated quantum photonic platforms, modular quantum sources and memory units, towards a secure interconnected quantum network. The scientific Thrusts of this QuIC-TAQS team is complemented with training of a diverse workforce, with priority emphasis on underrepresented graduate and undergraduate students. This involves recruitment from minority undergraduate and community college research site programs, focused mentorship efforts at UCLA-Colorado-Caltech in quantum science and technology.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

最近的努力已经证明了固态量子比特，原子量子比特，量子传感平台和固态合奏之间的显着互连。这不仅提供了下一代可扩展的紧凑型量子微处理器，而且为量子状态传输，传感，计算和通信的变革性互连量子网络奠定了基础。从社区最近展示的量子芯片内互连和处理器开始，该团队领导并推进了量子通信和互连的跨学科前沿-分布式纠缠和互连量子网络。这得益于该团队在量子通信的高维时频量子比特、基于稀土离子的量子存储器对网络链路中的中继器的自旋光子读出、独特的纠错算法和编码以及基本理论界限和数值计算方面的实验贡献。跨学科的努力跨越应用物理，化学，电气计算机工程，材料科学，数学和物理。与我们的行业和国家实验室同事一起工作，这个团队的努力允许检查互连的量子网络性能参数，即使在存在非理想的情况下。这个QuIC-TAQS团队研究了三个协同推力，以建立芯片可扩展的互连量子网络的交叉基础。在Thrust I中，QuIC-TAQS团队研究了具有集成芯片测量的高维高速率量子光子发射器。这包括高速率链路编码中的8192-Hilbert空间维度，以及贝尔状态测量和低抖动检测。沿着。在Thrust II中，QuIC-TAQS团队在UCLA和加州理工学院的联合测量中检查了高保真高效芯片级量子存储器。这是基于对网络中继器的动态控制的固态铒离子。将研究独特的协议和相干时间改进。在Thrust III中，QuIC-TAQS团队检查了强大的量子链路，包括编码和架构，以在加州大学洛杉矶分校建立量子网络测试平台。支持的测量，协议的改进和网络性能的数值模拟将被检查。所研究的QuIC-TAQS目标涵盖集成量子光子平台、模块化量子源和存储单元，以实现安全的互连量子网络。这个QuIC-TAQS团队的科学推动力与多元化劳动力的培训相辅相成，重点是代表性不足的研究生和本科生。这包括从少数民族本科生和社区学院的研究项目中招募人员，在加州大学洛杉矶分校-科罗拉多州-加州理工学院集中指导量子科学和技术。该奖项反映了NSF的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
