How It Would Work: Creating a Quantum Computer -- Popular Science
A working, large-scale quantum computer is still a decade away, but researchers are currently turning a critical corner from theory to building the first small quantum systems.
Silicon semiconductors have taken us a dazzling distance along the computing road. But even if they continue unabated to get faster and more powerful (and it’s growing more difficult to make that happen) there’s a limit to what classical computing can do.
