At 2minutes 17 seconds in this video delighted to see photo showing 3 Post Office Engineers (standing right is my great grandfather, Joseph William Willmot, Superintendent and Inventor) experimenting with signals across open water in Cardiff, Wales, 1897. He helped Marconi tune his equipment under the authority of Sir William Preece (Engineer-in-Chief of the Post Office Telegraph) UK.

I have a shrine of Claude Shannon in my condo.

I wonder how much Hickey Metal Fabrication paid for all 30 of the views this video has.

Now I see quantum computing will also mean quantum communications

So probably only a few people knew how to use them! 😛
