Of all the futuristic technologies being explored by big technology companies and start-ups, quantum computing is one of the most exciting. There are some types of computational problems that are simply impossible for even the world's most powerful supercomputer to solve. If you could pool all the traditional computing power in use today around the world, some of these calculations would take billions, trillions, or quadrillions of years to complete.Quantum computing offers a potential solution. The qubits ...
