Quantum Radio Prototype Receives Signals Over Long Distances in Border Exercises, Uses Miniaturized Reception Mechanism, and Advances the Integration of Quantum Technologies into Chinese Military Operations

China has begun testing a portable 3 kg quantum radio that received signals over several kilometers in remote border areas, as it seeks to enhance military communications when conventional antennas fail in critical terrain.

China has advanced the practical application of quantum science by starting tests of a portable device designed to enhance communications for units positioned in remote border areas, according to Science and Technology Daily.

The equipment is under evaluation by teams from the People’s Liberation Army, who are seeking alternatives for regions where standard systems frequently fail due to rough terrain or limited existing infrastructure.

Miniaturization of the Reception Mechanism

Radio communication remains essential for long-distance links as it traverses obstacles more efficiently, even though it required large antennas that reduced troop mobility on the front lines.

Traditional antennas take up significant space and incur additional costs, as well as complicating rapid movements, which led the team to completely rethink the reception model.

Zhan partnered with a manufacturer to redesign the receiver mechanism, reducing the set to just a few centimeters and allowing for a lightweight device without significant loss of perceived signal strength.

The resulting prototype maintains sufficient power for practical field use and can be carried by a single soldier, preserving mobility and ensuring continuous operation in complex terrains.

After successful tests in the Saibei grasslands, north of the Great Wall, the team is preparing additional evaluations in coastal positions deemed of higher operational risk.

Zhan stated that the battlefield can be unpredictable but predictable in trends, advocating for intensified research to ensure the rapid arrival of effective equipment to the troops.

Quantum Technologies Enter Military Units

An unidentified officer from the Information Support Force stated to SCMP that the unit is accelerating efforts to incorporate cutting-edge technologies into military digital and cyber operations.

According to this source, devices based on quantum theory in the areas of communication, detection, and computation are gradually exiting laboratories and entering operational frameworks.

The officer emphasized that a new generation of equipment will emerge aimed at strengthening the military’s cyber system, focusing on security and performance in the field.

China and the United States are heavily investing in quantum technologies, seen as capable of reshaping detection, cryptography, secure data transfer, and situational awareness in military environments.

Both countries assess that quantum devices could represent a significant strategic advantage in potential future disputes, enhancing monitoring capabilities and protecting critical information.

Growing Competition Between China and the United States

In recent months, China has unveiled various quantum innovations, including a mass-produced ultra-low noise single photon detector in October, designed to track stealth aircraft with greater precision.

Called a photon collector, the system identifies minimal units of electromagnetic energy and is compatible with quantum radar platforms and quantum principle-based encrypted communication.

A November report from the U.S.-China Economic and Security Review Commission noted that quantum computers will profoundly affect communications and data security while generating important military advantages.

The document highlighted that the United States leads much of the quantum research but acknowledged that China has mobilized industrial-scale funding and centralized coordination to advance quantum systems.

The commission assessed that China leads in quantum communication and is rapidly progressing in computing and sensing, driven by integration among state laboratories, defense-related companies, and PLA demands.

The report concluded that China’s pursuit of quantum technologies aligns with national security objectives, indicating a trend of continued expansion of these tools.

Additional elements of the document mention that cooperation between state and military sectors accelerates the practical application of research, expanding quantum presence in critical operations, which has generated some technical debate.

The final assessment reinforces that the transition of these technologies for military uses represents one of the central points of strategic competition between the two powers in recent years.

The Soviet Union spent 22 years drilling into the Earth’s crust and reached a depth of 12,262 meters — they found water where it was thought impossible, hydrogen bubbling from the rock, granite that is 2.7 billion years old, and temperatures of 180 degrees that melted the drill bits.

Egypt wants to draw 10 million cubic meters of water from the Nile per day into the desert, irrigate a new agricultural frontier, and build a city where there is currently only sand.

BRICS is preparing a payment system inspired by the Brazilian PIX that will allow direct transactions between countries using national digital currencies without relying on the dollar or Western banks as intermediaries.

Ethiopia has banned gasoline and diesel cars, placed over a hundred silent electric buses on the streets of Addis Ababa, and now aims for half a million electric vehicles by 2030, all powered by Africa’s largest dam and a courage that few countries have shown.

Scientists develop innovative technology that allows storing digital information and passwords using human hand gestures.

War in Iran and risk in Hormuz cause a 31.47% drop in Brazil’s exports to the Gulf in March, with corn almost zeroed out and sugar in sharp decline, while more expensive freight and longer routes hinder agribusiness shipments.

China delivers in Dalian its first 16-meter, 1,600-ton 8G95 LNG dual-fuel marine engine, with 74,725 hp, for container ships of up to 24,000 TEUs and EGR that meets IMO rules without extra equipment.
