Quantum network control is a major research area of the QUANT-NET project. We strive to build a quantum network control plane to orchestrate and manage all the physicallayer technologies, and to explore what a quantum network control plane should look like in the future, so as to automate high-rate and high-fidelity entanglement generation, distribution, and storage in an efficient, reliable, and cost-effective way. To these ends, we have designed a two-level control framework for quantum networks. Within such a framework, a two-level scheduler has been implemented to support synchronous time slot scheduling, network-wide non-real-time control, and nodewide real-time control. This two-level control framework and the scheduler are being deployed and evaluated in the QUANTNET testbed. Enabled by this two-level control framework and the scheduler, several basic quantum network operations have been automated in the testbed, which include automated quantum node calibration and on-demand single photon generation. In this paper, we present this two-level control framework, the scheduler, and the automated quantum network operations that have been enabled in the QUANT-NET testbed.
