“Exploring Quantum Technologies: Computation, Communication, and Sensing,”

This talk explores the major frontiers of the Second Quantum Revolution from a quantum hardware perspective, focusing on how the future of quantum technologies will be shaped. I present a forward-looking view of how the three foundational pillars—quantum computation, quantum communication, and quantum sensing—are co-evolving toward scalable and practically deployable quantum infrastructures. Within this framework, I highlight selected examples from my own work, including spin–photon interfaces in silicon for scalable quantum computing architectures and quantum networking, erbium-doped nanoparticle single-photon sources for telecom-band quantum communication, and a levitated superconducting particle coupled to a superconducting qubit as a platform for macroscopic quantum control and ultra-sensitive quantum sensing.
