Frikkin Space Lasers !

Near enough speed of light too...unlike that sluggy optique fibre 😂
which would be a thing if it operated in a vacuum, sadly the ISS is only at 400km altitude. The relay is at 40,000km so that might be closer to 0 Pa

Infra red laser as well, which *is* interesting.

Theres very little difference between the refractive index of air versus vacuum - I believe the slowdown is something like three ten-thousandths of the speed of light. So neglible really. Whereas light in fibre is appreciably slower, like 30% slower.

I suppose it doesn't really matter for what they want to do with it, but was one of things touted when they were looking at satellite to satellite laser links versus a pure terrestrial / submarine type optical link.

I looked it up, and saw that Erwin Schrödinger was involved so scrolled straight on by...
Very wise

Simply put at a quantum level they can control the way these particles spin at great distances, so if you have 8 particles and say a spin to the left is on and a spin to the right is off you have 8 bit binary and so on.

That is the full extent of my understanding 😂
 
What I really what to know is how much involvement *leading* British ISP's had in the scoping of this system.

It's so highly asymmetric (1.2Gbps down, 54Mps up) I'd imagine Virgin Media wrote the URS

I doubt any ISP has this on their radar 😂

Virgins approach will be how can we do Quantum entanglement on coax😂
