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

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 ...

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

Quantum satellites are best known for sending entangled particles of light from orbit down to ground stations, a method used to create extremely ...

A new study shows that satellites can create high-quality entanglement from photons sent up from Earth. Canada's Florida ...
