Quantum computers could expose our digital secrets – but there are much better reasons to build them
The Q System One quantum computer built by IBM, photographed at an electronics show. Audio und werbung / ShutterstockQuantum computers are coming. Or, at least, that’s what current predictions say. These machines harness the power of quantum mechanics, the set of rules governing how physics operates at atomic and sub-atomic scales. Because of this, they operate in radically different ways to current machines. Tasks requiring trillions of years on existing supercomputers might be reduced to day...
