For years, physicists treated an Earth-to-space quantum uplink as a beautiful idea that nature simply would not allow. Now a ...

A major breakthrough in quantum technology was achieved in October 2024: the first-ever quantum satellite communication link between China and South Africa. The connection spanned a remarkable 12,900 ...

Researchers have shown that quantum signals can be sent from Earth up to satellites, not just down from space as previously ...

For years, scientists have imagined a future where secure quantum links circle the planet from space. Satellites would create pairs of entangled photons and send them down to distant stations on Earth ...

The SpeQtre satellite carries advanced quantum hardware designed by SpeQtral to explore secure space-based quantum communications. It represents a notably difficult technical challenge – demonstrating ...

The discovery that roughly half of all geostationary satellite signals transmit sensitive data without encryption represents a critical failure that extends beyond today's threats into the quantum ...

Second, large-scale investment is arriving through national quantum-secure communication initiatives, from Europe’s EuroQCI ...
