Dr Simmons is a pioneer leader in single atom cryogenic qubit construction.  She gave an excellent research status report last year ...



Basically a working quantum computer is special purpose, it invalidates conventional public key (prime number pair) encryption.  This forces a restoration of equilibrium using quantum communication, the combination making a quantum internet, that restores the privacy that will be lost with a quantum computer working against the conventional internet.

The way my brother explained it to me a while back is a 64 bit wide quantum processor could solve a 64 bit encryption key in a single pass. With a 3 Ghz processor speed it would take about 0.000000000333 seconds to solve.

That is true for particular kinds of problems.  It is particularly useful against vulnerable encryption (which is only protected by length of time to compute).

It wouldn't make any difference to your Word document.

The safest thing is to keep all your important stuff on an offline computer...  Interconnectability is vastly over-rated.  Paper records are also viable, LOL!

Correct, my old boss, and a college professor, never let his company get directly connected to the Internet, and that was in 1991.  But now, like with some games, the app won't work without connectivity.  See Office 365.  You are owned, unless you can still use a pencil and paper.

There was not much internet in 1991.  But my strategy since it worked has been to divide my usuage among many info-stealing platforms and fake names a lot.  I get few ads...

You are not a Millennial/X-Gen.  These guys have no balance between "latest everything" and security risk.  They are happy for China and everyone else to read all their traffic (Huawei).

Can't disagree with you about that...
