A quantum-information physicist whose work spans the foundations of quantum-state manipulation and collaborative experiments in long-lived optical storage for quantum communication.
Light: Science & ApplicationsarXiv / Nature CommunicationsGuo’s contributions connect theoretical questions about quantum states with experimental components for communication. His work with Luming Duan explored probabilistic cloning under specified conditions, while later coauthored research demonstrated hour-scale coherent optical storage in a solid-state memory. These are different kinds of progress: one clarifies what quantum mechanics permits, and the other improves a physical resource that communication schemes may require. Neither should be confused with unrestricted cloning or an already deployed global quantum network.

Probabilistic cloning of quantum states
In an original interview, Guo describes his work with Luming Duan on probabilistic quantum cloning. The result concerns cloning specified sets of states with a success condition; it does not allow arbitrary unknown quantum states to be copied deterministically.
Joint theoretical work with Luming Duan, described in Guo’s original interview.

Hour-scale coherent optical storage
Guo coauthored an experiment reporting coherent storage of light for over an hour in an atomic-frequency-comb memory. The team combined a protected magnetic-field condition with dynamical decoupling, developing a resource relevant to long-lived quantum-memory proposals.
Coauthor with Yu Ma, You-Zhi Ma, Zong-Quan Zhou and Chuan-Feng Li; storage performance is a team result.

Keep in perspective
A narrow professional identification is used; no unverified current administrative title is asserted. The optical-storage result is not described as demonstrated hour-long storage of an arbitrary single-photon qubit.
