Trapped-ions is an ideal platform for quantum information processing and precision measurements. In this experiment, we focus on building a small-scale quantum computer/simulator with Be+ ions to investigate novel gate schemes, digital-analog quantum simulation of spin models, classical-quantum optimization problems, open system engineering etc… Besides, we’re interested in quantum-enhanced metrology and quantum sensing through spin-phonon entanglement.
Here are some researchs that we currently work on:
Develop quantum error correction techniques with trapped ion systems, including Steane method, subsystem code and hypergraph product code. Demonstrate high fidelity logical quantum operations
Demonstration of practical quantum algorithms(QAOA,VQE).
High fidelity Mølmer Sørensen gate in long ion chain with individual addressing beams (all to all fidelity>99.9%).High-Fidelity Detection
Use optical tweezers to engineer the motional spectrum.
