Overview of Academic Research
Prof. Xiu-Hao conducts systematic research in the field of quantum computing and quantum simulation, focusing on overcoming core challenges such as programmable manipulation of many-body quantum systems, fault-tolerant architecture design, and physical implementation from the perspective of quantum dynamics, and achieve the following key results:
Propose a geometric theory of quantum dynamics and control, which can be applied to study robust quantum control, error-correcting quantum circuits, quantum precision measurement, and sensing, and experimentally realize high-fidelity and high-robustness quantum gates and quantum circuits.
Conduct in-depth research on few-body and many-body quantum dynamics, including the geometric properties, statistical properties, and phase transitions of dynamics. Through theoretical and experimental studies on the dynamical properties of low-dimensional many-body quantum systems, reveal new mechanisms of non-equilibrium quantum thermalization and prethermalization dynamics.
Investigate solid-state quantum bits in depth, proposing multiple physical qubit schemes, control methods, and error-correction schemes to counteract noise.
Develop various quantum control algorithms, multi-qubit simulation systems, and open-source code libraries.
Core research directions:
1. Dynamical properties, manipulation, and error correction of quantum systems from few-body to many-body
2. Hardware-algorithm co-design for quantum computing
3. Physical problems in qubit systems
4. Quantum simulation and research on quantum computers with non-gate circuits
