A future quantum computer could potentially solve problems that are essentially impossible for even the most powerful supercomputer. The magic comes from the nature of quantum physics. While traditional computers operate on bits that can be in only one of two states, a quantum qubit is probabilistic, occupying some combination of those two states. This property opens the door to exponentially faster computations.Today's quantum computers generally aren't capable of solving real-world problems quicker than t ...
