PLA Tests Portable Quantum Radio Prototype as China Pushes Next-Gen Battlefield Communications
China’s People’s Liberation Army is testing what appears to be one of the world’s first portable quantum radio communication devices, marking a significant step toward next generation secure communications on the battlefield. According to a report by Science and Technology Daily, frontline border patrol units under the PLA’s Information Support Force recently carried out successful field trials of a miniaturised quantum communication prototype designed for difficult and obstructed terrain.
The device, which weighs around three kilograms, was able to receive quantum-based radio signals from distances spanning several tens of kilometres. Engineers involved in the trial said the team successfully decoded lines of transmitted information in real time, demonstrating the device’s ability to maintain stable communication despite environmental challenges. While the PLA did not disclose the exact testing locations, the report emphasized that the trials were performed in areas meant to simulate conditions faced by units deployed near China’s mountainous and heavily forested border regions.
Quantum communication, unlike traditional radio technologies, uses the principles of quantum mechanics to transmit information with extremely high levels of security. Its resistance to interception, signal degradation and electronic jamming makes it especially valuable in modern combat environments where adversaries can deploy advanced electronic warfare capabilities. The PLA has already invested heavily in quantum satellites and fibre-based networks, but the development of a portable device signals an effort to bring quantum technology directly into field operations.
Engineer Zhan Zihao, who worked on the prototype, said the successful experiment opens new possibilities for frontline communication systems. He explained that future versions of the device could support emergency communications in areas where conventional radio signals are unreliable or blocked, such as deep valleys, rugged mountains and dense forests. These environments often weaken or scatter radio waves, making secure communication more difficult. Zhan said the prototype showed promising performance in maintaining consistent signal reception even under such conditions.
Military analysts note that if fully deployed, the technology could give the PLA a meaningful advantage in securing battlefield communications, especially in regions where terrain complicates traditional systems. Portable quantum radios could allow small units to transmit sensitive information without fear of interception, while also reducing the risk of enemy tracking or signal disruption. The technology may also support broader efforts to integrate AI assisted command systems, autonomous platforms and digital combat networks.
For now, the device remains in the testing stage, and no timeline has been given for wider deployment. The PLA’s Information Support Force is expected to continue field trials, refine the design and evaluate how the technology can be integrated into existing communication networks. Analysts say miniaturisation, durability and energy efficiency will be key challenges before the system can see operational use.
The experiment adds to a growing list of China’s quantum research breakthroughs, highlighting the country’s ambition to lead in strategic technologies that could shape future warfare.
