Quantum Optics and Information
This area focuses on exploring the fascinating phenomena that arise when individual quanta of light, known as photons, interact with various forms of quantum matter such as atoms, molecules, mechanical oscillators, superconducting circuits, and even the environment. Our research groups delve into a wide range of topics, including quantum sensing, quantum super-resolution, quantum imaging, quantum measurement, condensation and superfluidity, quantum gravity, quantum navigation, wave-particle duality, single photon interferometry, cavity quantum electrodynamics, quantum noise, quantum-classical boundary, quantum information processing and computing.
Gravity-Quantum Interface
Quantum theory and gravity are both well-tested and well understood individually, but understanding their interface is one of the main challenges of modern physics. The advent of quantum technologies and the study of fundamental physics from the perspective of quantum information science has opened the door to explore this field from new perspectives. We study how gravity affects the dynamics of quantum systems, possible signatures of quantum gravity at low energies and how to use novel quantum technologies to probe how gravity and quantum mechanics meet in experiments.
Photonics and Quantum Materials
We synthesize and assemble novel 2D materials that are atomically thin metals, insulators, semiconductors, or ferromagnets and integrate them into on-chip quantum-photonic, nonlinear-optic, and nano-electronic devices. We also employ symmetry considerations and machine learning algorithms to design and develop novel functional devices and study fundamental properties of quantum materials at high magnetic fields and at cryogenic temperatures. These quantum materials are of vital importance for technological applications such as light manipulation, information processing, energy harvesting, or quantum sensing.
