The Algebra and Its Applications team from the College of Mathematical Sciences has recently introduced the concept of embezzling catalysts into quantum communication, significantly enhancing the transmission capacity of quantum information. Their groundbreaking research, titled "Teleportation with Embezzling Catalysts," has been published in Communications Physics, a sub-journal of Nature.
XING Junjing, a doctoral student from the team, served as the paper's first author. The corresponding authors include two faculty members from the College of Mathematical Sciences and collaborators from the Beijing Computational Science Research Center and the Singapore Institute of High-Performance Computing. Harbin Engineering University is the lead institution for this research, which was supported by grants from the National Natural Science Foundation of China.
Efficient information transmission is pivotal for advancing technology and driving scientific discovery. Quantum communication, with its superior security and efficiency compared to classical methods, has revolutionized the field of communication technology. Teleportation protocols, in particular, are essential for transmitting information in quantum systems.
To date, quantum teleportation protocols have been successfully implemented using low Earth orbit satellites, achieving communication distances of up to 1,400 kilometers—an achievement that lays the groundwork for a global quantum network. However, environmental noise often compromises the efficiency of quantum communication. To address this challenge, the team drew inspiration from chemical catalysis, where the deactivation of catalysts sometimes leads to unexpected outcomes. They explored the use of embezzling catalysts with minor imperfections in quantum communication. Their findings demonstrate that teleportation protocols assisted by embezzling catalysts can nearly perfectly transmit quantum information even in noisy environments.

The Algebra and Its Applications team focuses on solving advanced problems in algebra. Recognizing the strategic importance of quantum information research, the team has integrated representation theory into their work on quantum information over the past three years. This interdisciplinary approach addresses fundamental challenges in quantum resource theory, quantum computing, and quantum information. Their efforts align with national priorities and aim to push the boundaries of both algebra and quantum research.
