FTL communication using quantum entangled particles.
Not possible; entanglement collapse can’t be used to send information
The idea is this:
2 particles are quantum entangled. Whatever happens to one instantly happens to the other regardless of distance.
So you establish a state that means “0” and a state that means “1” and you can send binary.
At a minimum, you have quantum Morse code.
I’m familiar with quantum entanglement. It doesn’t work because you have no way of affecting which state you’ll measure, and thus what state the other particle will be in.
Read the link posted. They already did it. In 2007. At a distance of 144km.
No they didn’t, they sent a conventional signal that was encrypted with an entangled particle. Nothing was sent ftl, this is like if I had two boxes that I know have the same thing in them, an encryption key, and traveled across the world, and sent you a message, you have the other box, the information in that box didn’t go ftl you just opened it later.
there is no path to ftl communication here.
have a basic video on the topic: https://www.youtube.com/watch?v=9oBiS_Yb9Ac
The FTL is the sci-fi component that is the subject of the thread, the quantum entanglement communication part is the real world piece they actually got working.
It will never be possible to use this for ftl communications. This is like saying in 100 years we will use very long steel rods to communicate ftl by pushing on them. The problem is fundamental.
