Quantum computing will enter the mainstream faster than most of us realize, a panel of experts told a San Francisco crowd earlier this week — with some important real-world applications emerging within five years.

Why it matters: Quantum computers won't replace the semiconductor-based electronic computers we live with today, but they might speed up the solving of fiendishly difficult problems in fields like molecular imaging, cryptography, probability and artificial intelligence. Once they do that, they will make fortunes, disrupt businesses — and open the door to a host of potential new problems.
