Since 1987, he has been a professor with Tsinghua University. During 1989 and 1993, he was a research fellow with the University of Sussex, Brighton, U.K. His research interests include quantum communication and computing and optical microcavity. Notably among his various contributions, he proposed the theory of quantum secure direct communication in 2000, which is one of the three major quantum secure communication theories; constructed a quantum exact search algorithm, sometimes called Grover–Long Algorithm; and established the linear combination unitaries method, which is widely used in quantum algorithm designs. He has authored or coauthored more than 300 papers in refereed international journals. Dr. Long is a Fellow of IoP (U.K.) and Fellow of APS (U.S.A.). He was the president of Associations of Asian Pacific Physical Societies (2017–2019) and the vice-chair of C13 of IUPAP (2015–2017).
