可扩展量子计算机的互连网络

Interconnection Networks for Scalable Quantum Computers

Nemanja Isailovic, Yatish Patel, Mark Whitney, John Kubiatowicz

摘要:

我们表明,量子计算机中的通信问题归结为通过分布高保真EPR对来构建可靠的量子信道。我们开发了这些通道的延迟,带宽,错误率和资源利用率的分析模型,并表明必须分布100个量子位才能容纳单个数据通信。接下来,我们表明,一个网格的隐形传态节点形成了一个很好的基板上分布EPR对。我们还探讨了这样一个网络的控制要求。最后,我们提出一个特定的路由架构,并模拟量子傅立叶变换的通信模式,以展示资源竞争的影响。

英文摘要:

We show that the problem of communication in a quantum computer reduces to constructing reliable quantum channels by distributing high-fidelity EPR pairs. We develop analytical models of the latency, bandwidth, error rate and resource utilization of such channels, and show that 100s of qubits must be distributed to accommodate a single data communication. Next, we show that a grid of teleportation nodes forms a good substrate on which to distribute EPR pairs. We also explore the control requirements for such a network. Finally, we propose a specific routing architecture and simulate the communication patterns of the Quantum Fourier Transform to demonstrate the impact of resource contention.
