Quantum Information Science and Many-Body Physics with Single Quantum Entities
In Quantum Information Science (QIS), to fully harness the power of quantum mechanics, the platform has to be a many-body system with interacting or coupled single quantum entities (or qubits). Experimentally understanding new principles and laws in few- and many-body systems is essential for both solving interesting puzzles in fundamental many-body physics and ultimately providing practical solutions for important technological applications in many fields including QIS.
The research in my group focuses on experimental studies of many-body quantum systems by using advanced laser spectroscopic techniques. Recent advances in the preparation of exotic single quantum entities (single atoms and atom-like entities) and in coherent spectroscopy provide unprecedented opportunities in the field. In our studies, we deterministically prepare a few- or many-body quantum system of single quantum entities using a bottom-up approach (e.g. cold atom arrays trapped in optical tweezers and color centers in diamonds) and use the system for studying many-body properties and realizing applications in QIS.
