LAMP-WEBINAR

Quantum technology harnesses fundamental principles of quantum mechanics, such as superposition and entanglement. Research in quantum science and technology is advancing rapidly. Various platforms are being explored to scale quantum technologies, including atomic traps, ion traps, cavity quantum electrodynamics (QED), circuit QED, and hybrid quantum systems. The generation, manipulation, control, and transmission of quantum states are fundamental requirements of quantum technology. Among these platforms, cavity QED is a powerful method that can fulfill all these requirements. Cavity QED was first experimentally realized at the single-atom and single-cavity level during the 1980s and 1990s. In the early 2000s, it was extended to solid-state systems, by coupling self-assembled quantum dots to photonic crystal cavities and by coupling superconducting qubits to microwave cavities. Hybrid quantum systems have also emerged as a promising platform, leveraging the unique properties of individual quantum systems. In this talk, I will present highlights from my research, specifically on quantum logic gates utilizing multi-qubit cavity QED systems. In the latter part of the talk, I will briefly discuss quantum imaging with undetected photons and outline future research directions involving cavity QED, hybrid quantum systems, and quantum imaging techniques.
