Scientists have successfully established the world's longest intercontinental ultra-secure quantum satellite link, spanning 12,900 km. Using the Chinese quantum microsatellite Jinan-1, launched ...

A small quantum satellite created a secure link between ground stations in China and South Africa, sharing quantum-encrypted data over a record distance of 12,900 kilometres. Similar ...

Now, however, Chinese researchers have made a major breakthrough by developing the world's first quantum microsatellite and demonstrating real-time QKD between the satellite and multiple compact ...

The satellite was able to send pulses of laser light, put into special quantum states, from a rooftop in Beijing to another at Stellenbosch University near Cape Town. The pulses formed a quantum ...

A research team has developed the world's first quantum microsatellite and demonstrated real-time quantum key distribution (QKD) between the satellite and multiple compact, mobile ground stations.

The information itself is classical – in this case, photos of the Great Wall of China and Stellenbosch – but it’s encrypted through quantum key distribution (QKD). The satellite encodes ...

Quantum network is step towards ultrasecure internet The satellite, called Jinan-1, is ten times lighter, 45 times cheaper and much more efficient than its predecessor, Micius, which launched in ...

To determine if that is the case, the research team obtained radar-based satellite data for the years 2016 through 2020. Such radar is able to measure ground height to the millimeter. In comparing ...

China successfully sent quantum images to the opposite side of the Earth using a super-small satellite. By significantly reducing satellite costs compared to the past, the communication distance ...

A spinoff from Singapore's Center for Quantum Technologies (CQT), SpeQtral is developing a satellite-based QKD system for secure communication and cybersecurity. SpeQtral is working on two QKD ...

Implementation of the first quantum satellite link in the Southern Hemisphere at Stellenbosch University, South Africa. The microsatellite, Jinan 1, launched in the lower earth orbital ...
