If you want a fun rabbit hole to go down, I highly recommend researching more about quantum computing.

I’m not an expert and I cannot claim to know anything with 100% certainty, but a lot of it doesn’t make any sense. I’d put my skepticism on the same level as your skepticism about nukes.

Essentially, the only way they would work is by having large sets of QBits entangled in a state of quantum superposition, running a function, and then making a measurement. But the problem is that even though you can get exponentially more efficiency with more QBits, you also have to make an exponentially increasing amount of state measurements.

Modern quantum computers get around this by being

1. Really small and inefficient

2. Segmented into separate sections instead of all entangled together

But there isn’t any known way to make enough state measurements to make them useable to crack sophisticated encryption in reasonable times.

Just my two sats though - definitely DYOR.
