In the race to lead quantum computing, some big technology companies and startups are discovering that the road to market remains longer than planned despite years of often heavy investment. Quantum computers promise a leap in number-crunching by using atom-size particles instead of transistors. In theory, the enhanced processing power could help lead to the discovery of new drugs by running simulations of protein interactions that are too complex for current computers to work through. Or they could crack standard encryption...
