Synergistic Integration of Metamaterials and Quantum Photonics as a Pathway for the Quantum-Enabled Internet

The future of quantum networking hinges on advancements in materials that can efficiently generate, manipulate, and transmit quantum information. This talk will explore how the integration of quantum photonics with metamaterials [1]—engineered sub-wavelength structures—offers new avenues for creating robust, scalable quantum networks. Key research highlights include the development of metamaterials that enhance single-photon and multi-photon generation, entanglement distribution, and quantum state manipulation.

We will discuss the latest progress in quantum metasurfaces and integrated photonic circuits, focusing on their role in creating high-fidelity, room-temperature single-photon sources and scalable entanglement platforms. By leveraging the unique electromagnetic properties of these materials, researchers have achieved precise control over photon emission and interaction, paving the way for efficient quantum repeaters and routers. These components are crucial for realizing long-distance quantum communication and ultimately establishing a global quantum internet.  We will also highlight progress made in hardware-aware studies of quantum algorithms using a THz metasurface-based emulator [2].
