Nations across the globe have realized the importance and implications of a quantum internet and are committed to its development. Development, interest and progress have continued even throughout the global pandemic. This includes the USA National Quantum Initiative Act, the Netherlands National Agenda for Quantum Technology and the Quantum Science Experiment Satellite launched in China. Canada is well positioned to be a key player and leader in the global quantum ecosystem as we are home to multiple quantum powerhouse institutions (UWaterloo, UCalgary, UOttawa, NRC). Furthermore, unique and collaborative training programs will need development to meet Canada's need for HQP in quantum networks and to ensure the prosperity of Canada's emerging quantum technology sector.A quantum internet is a lofty goal demanding intense efforts. Successful implementation of such a network will require careful design composed of highly specialized components. A primary challenge is that not only must these specialized technologies integrate with each other, but also integrate with existing telecommunication infrastructures. The research goals delineated in this program addresses the scientific and technological issues that will make this transition possible. We focus on developing the robust and widely deployable quantum communication technologies that can comprise the future quantum internet in Canada. The research goals of this work seek to overcome these challenges by developing devices necessary for an interoperable quantum network that operates at room temperature. Leveraging the expertise across three institutions, we develop a theoretical framework that simulates a quantum light source and its interface with a deployable quantum memory system. Further, we verify the interoperability of our devices through a series of first-of their kind interfacing experiments between devices developed across the institutions.
