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 ...

IBM Quantum roadmap, processors, and infrastructure outline clear path to IBM Quantum Starling, expected to be first large-scale, fault-tolerant quantum computer  Breakthrough research defines key elements for an efficient fault-tolerant architecture — charting the first viable path toward a system projected to run 20,000 times more operations than today's quantum computers Representing the computational state of IBM Starling would require the memory of more than a quindecillion (1048) of the world's most ...
