Quantum computers can solve problems that would take an ordinary computer millions of years to complete. It would take not thousands, but millions of years to create solutions to complex equations. Google and researchers at the University of California, Santa Barbara (UCSB) have just tackled the latest roadblock that was holding back quantum computing. They created program groups called qubits, which use delicate quantum physics to represent information. They programmed these qubits to identify and prevent calculation errors. Qubits haven't actually prevented initial bit-flip errors, but they prevent the mistake from derailing a calculation.
