Quantum computing sounds exciting... the press release said today 20,000 times faster than current supercomputers. That's fast, and nice to know more than one or two customers are able to purchase, install, and begin programming them THIS YEAR.
The implications for the future of cryptocurrency are clear-- quantum computers are legendary for cryptology computations.
Whether or not BTC is going to be the future of payment itself is, to me, less clear, but still more interesting now that alternative information processing devices are considered a logical investment to some very logical customers.
At first, programmers need to figure out how to utilize the physics to accelerate computation. It's a different paradigm, and the gamble is how talented will we be at riding the quantum wave.
