Photons

Scientists in China teleport first object 300 miles into space!

Scientists in China teleport first object 300 miles into space!

Last month, the Chinese team demonstrated they could send entangled photons from space to Earth. The latest work does the reverse: they sent photons from the mountaintop base to the satellite as it passed directly overhead.
