一种量子逻辑阵列微体系结构：可扩展的量子数据移动和计算
A Quantum Logic Array Microarchitecture: Scalable Quantum Data Movement and Computation
摘要：
最近的实验进展已经证明了能够支持可扩展量子计算的技术。下一步的关键是如何将这些技术整合到一个可扩展的容错系统中，这也是可行的。我们提出了一个量子逻辑阵列（QLA）的微架构，形成这样一个系统的基础。QLA侧重于有效支持容错计算所需的通信资源。我们利用广泛的基础量子纠错理论，并提供分析，表明我们的系统是渐进和经验容错。具体来说，我们使用QLA实现了一个分层的，基于阵列的设计和对数费用量子隐形传态通信协议。我们的目标是克服困扰当前大规模量子计算提案的可靠性、通信和量子资源分配的主要可扩展性挑战。
英文摘要：
Recent experimental advances have demonstrated technologies capable of supporting scalable quantum computation. A critical next step is how to put those technologies together into a scalable, fault-tolerant system that is also feasible. We propose a Quantum Logic Array (QLA) microarchitecture that forms the foundation of such a system. The QLA focuses on the communication resources necessary to efficiently support fault-tolerant computations. We leverage the extensive groundwork in quantum error correction theory and provide analysis that shows that our system is both asymptotically and empirically fault tolerant. Specifically, we use the QLA to implement a hierarchical, array-based design and a logarithmic expense quantum-teleportation communication protocol. Our goal is to overcome the primary scalability challenges of reliability, communication, and quantum resource distribution that plague current proposals for large-scale quantum computing.
