Quantum Light-Matter
group
group
We are a theoretical research group focused on Quantum AI, Strong light-matter interactions, and their Applications across various disciplines. Our work investigates physical systems such as semiconductor microcavities, quantum dots, and related light-matter platforms.
Openings for Ph.D. and M.Phil. Students
We are actively looking for highly qualified and motivated graduate students to join our team. A few openings are available.
Students with a strong interest in quantum machine learning, quantum optics, or strong light-matter interaction are welcome to apply. Research experience in related fields is a plus.
To apply, please send your CV, academic transcripts, English proficiency test scores (TOEFL/IELTS/CET-6/CET-4), and any other relevant materials.
We are especially seeking excellent Ph.D. candidates from top 50 universities or candidates with exceptional research records.
Interested candidates should email us at sanjibghosh@cuhk.edu.cn
Undergraduate Students
We welcome undergraduate students with a strong interest in quantum optics, or quantum information to join our group. Interested students should email us at sanjibghosh@cuhk.edu.cn with their CV and academic transcript.
