AI Summary

In distributed quantum computing, high latency in remote quantum gate (telegate) and quantum data (teledata) transmission arises from synchronization constraints imposed by classical communication. Method: We propose the first asynchronous telegate/teledata protocol, decoupling quantum operations from classical communication timing to hide entanglement distribution and measurement-feedback overheads. We introduce a non-unitary operator optimization framework to enhance fault tolerance and resource efficiency, and design a hardware-oriented quantum network interface card (QNIC) prototype architecture. Contribution/Results: Experimental and feasibility analyses demonstrate significant end-to-end latency reduction, alongside decreased photon distribution and classical signaling overheads. Our approach establishes a new low-latency, resource-efficient asynchronous communication paradigm for scalable quantum networks.

Abstract

The cost of distributed quantum operations like the telegate and teledata protocols is high due to latencies from distributing entangled photons and classical information. This paper proposes an extension to the telegate and teledata protocols to allow for asynchronous classical communication which hides the cost of distributed quantum operations. We then discuss the benefits and limitations of these asynchronous protocols and propose a potential way to improve these asynchronous protocols using nonunitary operators. Finally, a quantum network card is described as an example of how asynchronous quantum operations could be used.
