Crazing processing speed may be coming in unbelievable speed...if error/failure barriers have indeed been breached? (Interesting read) Brad

Hmmm. Bitcoin are "mined" by a computer solving a problem so difficult that it requires a lot of energy and computing power. Seems that a quantum leap in computing power could eliminate that difficulty? Just the musings of a non-technical mind, I don't understand any of this.

The value of cryptocurrencies derives from the difficulty of generating a solution, and the limit on the number of solutions (and, of course, the existence of people willing to exchange it for real stuff). A quantum solution to a conventional crypto algorithm would trash the value of the currency, unless it had all been 'mined'. No doubt if we see practicable quantum computers we'll see new algorithms that are difficult to mine. But if I had any old school Bitcoin I'd be worried about its long term prospects.
Also seems like maybe no password would be safe anymore if all possible combinations could be tried in moments?

Conventional passwords (at least 8 characters, upper and lower case, numbers and symbols) are surprisingly resistant to brute force solutions (about 8 to the power of 80 possibilities depending on allowable symbols). So I wouldn't worry that a quantum computer will hack into your BHO account any time soon. Decryption may be a different matter.
The problem is…energy/power to run this technology. So far, it would appear the infrastructure of America’s grid is so poor, even with a super effort and expense to add and connect grid with poles and wire and money, it is not possible to serve the upcoming technology. I doubt I will live long enough to witness the gridlock? Brad

The infinite speed of commercial quantum computers will arrive at the same time as the free and clean power of commercial fusion reactors. I'm not holding my breath for either.

A agree, mostly. And I doubt my next laptop will be "quantum" speed. Brad
