The University of Science and Technology of China published a review paper on space quantum experiments

A few days ago, Pan Jianwei of the University of Science and Technology of China and his colleagues Peng Chengzhi, Lu Chaoyang and Cao Yuan were invited to publish a long review paper entitled “Space Quantum Experiments Based on the Mozi Satellite” in the international authoritative review journal of physics, Modern Physics Review.

The paper comprehensively introduces the achievements of international space quantum science research in the past two decades, focusing on the “Mozi” quantum science experimental satellite from the early key technology research, including the construction and development of six major systems such as satellite systems and scientific application systems, to the systematic scientific research achievements achieved after the satellite is in orbit, providing valuable information for the international academic community.

The paper systematically expounds and summarizes the basic concepts of quantum information theory, early quantum communication and quantum information-related principle experiments, satellite-oriented ground large-space scale verification experiments, and the “Mozi” satellite from project establishment, development, orbit operation to finally the international first completion of a series of star-to-ground quantum science experiments.

At the same time, the review paper also sorts out the research progress of international space quantum science. The success of “Mozi” has stimulated the research boom of international space quantum science, and the United States, the European Union, Japan and other international forces have subsequently begun to explore their own wide-area quantum communication path, proposing or accelerating a series of space quantum science layouts.

At the end of the review paper, the main development direction of space quantum science is prospected, and it is proposed that space quantum science research will inevitably leap from low-orbit platforms to medium- and high-orbit platforms, and even deep space platforms. On this basis, taking advantage of the wide coverage, long experimental time and good microgravity environment of the medium and high orbit satellite platform, the space quantum communication technology is simultaneously applied to the fields of long-distance high-precision time-frequency transmission and space ultra-cold atomic physics, and more abundant scientific outputs are obtained in basic scientific problems such as quantum precision measurement, quantum physics and general relativity fusion.

It is reported that due to a series of pioneering work in long-distance quantum communication, especially the “Mozi” quantum satellite, Pan Jianwei and others were invited to write this 46-page review paper for the Modern Physical Review.

The Modern Physical Review is the most authoritative review journal in the international physics community, publishing only about forty academic papers a year. The journal generally does not accept freelance submissions, mainly invites physicists who have made achievements in various fields to write, aiming to make historical summaries, principle elaboration, current situation analysis and trend predictions on the major hot issues in today’s physics research. This paper is the third review paper published by Pan’s team in the journal, following “Multiphoton Entanglement and Interferometry” in 2012 and “Secure Quantum Key Distribution Based on Real-World Devices” in 2020.
