Research also suggests that these two factors -- more corruption, more social networking -- also correlate with lower suicide rates. |
| Scientists use 'voting' and 'penalties' to overcome errors in quantum optimization Posted: 06 Feb 2014 10:39 AM PST Seeking a solution to decoherence -- the "noise" that prevents quantum processors from functioning properly -- scientists have developed a strategy of linking quantum bits together into voting blocks, a strategy that significantly boosts their accuracy. In a new study, the team found that their method results in at least a five-fold increase in the probability of reaching the correct answer when the processor solves the largest problems tested by the researcher, involving hundreds of qubits. |
