You mean I do not have to fear someone driving through the neighborhood with a data center trying to crack my VPN.
re: “Quantum computing still has to overcome its interference, error correction, and scalability problems.”
Should remind one of the early hype surrounding ‘tunnel diodes’, diodes exhibiting the Esaki diode effect, a negative resistance in their V-I characteristic ... they were forecast to enable some aspects of high speed computing at the time (early 60’s).
We don’t use them today (in computers!) although Tektronix made widespread use of them in Oscilloscope triggering circuits for multiple decades ...
And I doubt my home system could handle such speed coming into it.
