QS Lab Mission: Engineering quantum states in novel solid-state materials and devices toward scalable computing, communication, and sensing platforms

The research theme is categorized into three phases as follows:

(1) Atomic-Layer Synthesis of 2D Quantum Materials

Focus: Large-area, phase-pure, and CMOS-compatible growth

Techniques: MOCVD, source-confined growth, and data-driven optimization

Materials: 2D Semiconductors, Ferroelectrics, Superconductors, and Topological materials

Goal: Precise control over thickness, phase, and interfacial quality for interface-ready vdW systems

(2) Programmable Quantum Emitters

Focus: Integrating lateral or vertical vdW heterostructures with electrically tunable order parameters

Physics: Deterministic single-photon emission, tunable excitons, and ferroelectric polarization

Goal: Developing nonvolatile and field-controllable quantum states for quantum photonics

(3) Quantum-Engineered Nanoelectronics

Focus: Room-temperature post-CMOS devices to cryogenic quantum circuits

Devices: Ferroelectric FETs, tunneling transistors, vdW Josephson junctions, and superconducting qubits

Applications: Classic-quantum interfaces, low-noise cryogenic electronics, and scalable quantum information processing platforms
