Now. I am no quantum Physicist so a whole bunch of this stuff, I simply can not understand. But, things I can understand are things like
An answer output can change, just by the act of Looking at it. That's pretty mind blowing.
With Quantum computing only just over the horizon, we are going to have to make ourselves aware of it and learn how we can work with/against it.
One problem posed by quantum computing, will be the safety of our Crypto Currency. With Quantum computing used along with Shor's Algorithm, the threat to our Crypto security is all too real.
Please familiarize yourself with this document.
I'm not going to sit here and explain it all, because quite frankly a lot of it is WAY over my head. But, there are definitely things that I can understand in here and I feel everyone should at least, dip their toes in the pond of this strange.
Please read, and maybe we can have some enlightened individuals share with us, what something like Shor's Algorithm means, for users in the Crypto Currency space.
