Laboratory Introduction
The Rydberg Quantum Technology Laboratory, established in 2007, focuses on frontier fundamental research and technological innovation by leveraging the unique quantum properties of highly excited atoms (Rydberg atoms).Rydberg atoms, with their electrons occupying extremely high principal quantum number orbitals, possess giant electric dipole moments, exceptionally strong interactions, and high sensitivity to external electromagnetic fields, making them an ideal platform for scalable quantum computing, quantum simulation, and quantum precision measurement.
Main research directions:
1. Coherent manipulation of the outer field of the Reedberg atom
(1) Achieving fast, high-fidelity two-qubit and multi-qubit quantum logic gates by exploiting the Rydberg blockade effect.
(2) All-optical quantum memory
2. Neutral atom arrays and quantum simulation
(1) Constructing controllable one-dimensional and two-dimensional atomic arrays.
(2) Investigating non-equilibrium dynamics, quantum coherence evolution, and thermalization processes to explore novel quantum matter states.
3. Quantum precision measuremen
(1) Leveraging the ultra-high sensitivity of Rydberg atoms to electromagnetic fields to achieve quantum precision measurement of microwaves, radio frequencies, and weak electric fields.
(2) Develop new types of atomic-level detectors.
4. Rydberg molecular and precision microwave spectroscopy
(1) Preparing novel Rydberg molecules and exploring their exotic physical properties.
(2) Combining microwave and multiphoton excitation techniques, high-resolution spectroscopy technology was used to analyze the intrinsic properties of Rydberg atomic molecules.
5. Rydberg Many-Body Interactions
(1) Investigating the interaction control mechanisms and techniques of Rydberg atoms
(2) Study kinetic processes such as time crystals, quantum quenching, and thermalization.
Technology and experimental platform
The laboratory is equipped with state-of-the-art core facilities including ultra-high vacuum systems, laser cooling and trapping apparatus, single-atom optical tweezer arrays, high-resolution optical and ion imaging systems.The self-developed control and measurement system enables optical manipulation, real-time data acquisition and feedback, providing a solid foundation for precisely investigating atomic interactions, exploring quantum dynamics, and developing novel quantum technologies.
