Current Research Areas

Quantum optics is a topic that studies the quantum properties of light and discusses the interaction between light and matter. It covers such as quantum physics, electromagnetism, and atomic, molecular, and optical physics (AOM). In addition, quantum optics also plays an important role in current quantum technology, such as all-optical quantum computing and quantum communication and sensing. Our laboratory will focus on using experimental technology and theoretical research of quantum optics to explore the important applications of quantum communication and solve the bottleneck of current technology in practice. Our research includes:

1. Frequency-encoding quantum information processing

2. Development and measurement of quantum entangled source

3. All-optical quantum repeater protocol

4. Novel quantum key distribution protocol

The above research topics involve optical systems such as nonlinear optical materials, solid-state systems, and semiconductor lasers. Furthermore, our work not only includes experimental research but also focuses on the establishment of theoretical models. We will also theoretically study quantum optics, AOM, and quantum information theory.  By combing theoretical research and experiments, the developed work not only contributes to quantum technology but also deepens our understanding of the nature of quantum mechanics deepen.
