Reconnect China Policy Brief 15: China's Quest for a Quantum Leap

Marc Julienne

Policy brief no.15 written within the Reconnect China Horizon Europe project deals with the intensifying global race to harness quantum science. Recognizing the strategic potential of quantum technology for economic, military, and scientific advancement, China is focusing on quantum breakthroughs as a way to shift the balance of power, especially in its competition with the United States. President Xi Jinping has emphasized the importance of scientific innovation, particularly in quantum fields, to fuel national development and ensure security. Chinese researchers, led by figures like Pan Jianwei, have made significant strides in quantum communication and computing. China is particularly advanced in quantum communication, building secure networks that use quantum key distribution (QKD), which is virtually unhackable. China has also launched quantum satellites, like Mozi and Jinan-1, to bolster its space-ground quantum network. Despite its achievements, China may face challenges in keeping up with competitors. The quantum industry lacks robust private investment and relies heavily on state support, while geopolitical tensions, particularly with the U.S., risk isolating China from essential technologies. The coming decade will be crucial as China continues to navigate these obstacles in its quest for quantum supremacy. Policy recommendations: Given the strategic reach and military potential of quantum technologies, and given the central role of the Party and state in the quantum industry in China, any European partnership with and investment in China should be scrutinized carefully Europe must keep up with quantum application developments and standardization so that it does not entirely rely on technology and norms developed by foreign powers in the future Europe may play a constructive role in preventing the fragmentation of norms between the US and China The policy brief is complemented by the relevant infographic (10.5281/zenodo.22555953).

The study of Quantum Physics in Space Technology

Shravani Raju Rupwate

Quantum physics has transitioned from a purely theoretical discipline to a transformative technological foundation influencing modern space science and engineering. From ultra-precise atomic clocks enabling global navigation systems to quantum sensors enhancing spacecraft navigation and quantum communication networks promising unbreakable encryption, quantum mechanics now plays a pivotal role in space technology. This research paper explores the theoretical foundations of quantum physics and examines its applications in satellite systems, deep-space exploration, communication networks, gravitational sensing, propulsion research, and cosmology. It further discusses current missions led by agencies such as NASA, European Space Agency, and China National Space Administration, highlighting advancements in space-based quantum experiments. The paper concludes with future prospects, technical challenges, and the role of quantum technology in shaping next-generation space exploration.

Progress of the Quantum Experiment Science Satellite (QUESS) Micius Project

Jian-Wei Pan

The Micius satellite was successfully launched on 16 August 2016, from Jiuquan, China, orbiting at an altitude of about 500 km. The main scientific goals, including satellite-to-ground quantum key distribution, satellite-based quantum entanglement distribution, ground-to-satellite quantum teleportation, and satellite relayed intercontinental quantum network, were achieved in 2017. As a starting point, the Micius satellite has become a platform for quantum science experiments at the space scale. Here, we introduce the latest experimental achievements (in 2018-2020) based on the Micius satellite.
