ExpandQISE: Track 1: Virtual Quantum Networks: From Foundations to Field Tests
Project Synopsis
The emergence of quantum networks has
sparked a technological revolution envisaged to shift the landscape of communication,
sensing, and computing in the forthcoming decades. While ongoing efforts in building
quantum networks are broad, immense, and even like ``arms race'', existing quantum
network systems are still local, small-scale, and application-specific
(e.g., designed for quantum key distribution), which is reminiscent of the era of
internet onset. Looking ahead, the expansion of quantum networks, if without thoughtful
planning, will inevitably lead us into the same pitfalls as classical
internet such as network ossification and resource wastes.
The goal of this project is to develop a general-purpose, open-access, and programmable quantum network prototype for the quantum information science and engineering (QISE) community to experiment new quantum technologies and train teachers/students of all majors, thereby accomplishing the vision of coordinating diverse research efforts and expanding the QISE workforce. The key methodology to be applied is virtualization that will turn a physical quantum network fabric into multiple independent software-controlled network overlays for concurrent and hardware-agnostic network access. An overview of the proposed research & education activities are displayed in Figure 1.
This project will be based on a
quantum network testbed in the University of Arizona (UA), which was developed by
co-PI Zhang's lab and colleagues. The testbed is shown in Figure 2.
Specifically, the INQUIRE testbed consists of 14 network nodes residing in 6 buildings
across
the UA campus, connected by more than 100 optical fibers and a free-space
line-of-sight link, as shown in Figure 2a. At present, the key
functionalities of INQUIRE include the generation and distribution of entangled-photons,
remote access to single-photon detectors, and scheduling and routing of quantum
resources. As a precursor of VQNs, the INQUIRE testbed currently serves as a
quantum internet service provider (qISP) that is fully automated and centrally
managed by the Agilent iLab platform. Quantum-network users remotely log into the
iLab platform to request access to the quantum resources including entangled photons
and single-photon detectors, as illustrated by Figure 2b. The qISP
of INQUIRE shares, manages, and maintains quantum resources for a large number of
network users in a time-multiplexed manner. The capability qISP of INQUIRE can be
substantially enriched by the new VQN architecture, protocols, and applications to
be pursued in this project.
