Simulations Show Quantum Error Not As Bad As Believed 44

aarondubrow writes "Because quantum systems become unstable quickly, their error threshold is an important factor. How many bits can 'break' before the system stops working? An international team of researchers used the supercomputers at the Texas Advanced Computing Center to simulate the error threshold of a topological quantum system and found a much higher threshold than had previously been reported."

Seasonal Flu Shots Double Risk of Getting Swine Flu, Says New Study 258

Posted by Soulskill from the twice-as-nice dept.
krou writes "A Canadian study currently under peer review apparently suggests that individuals given seasonal flu shots are twice as likely to get swine flu. The 'perplexing' study has thrown influenza health plans into disarray, with Quebec, Alberta, Saskatchewan, Ontario and Nova Scotia all suspending seasonal flu shots for anyone under 65 years of age. The study appears to be confined to Canada; the US, Britain, and Australia have not reported the same problem, so some are suggesting that the research has 'study bias.' However, the research appears to be 'solid' according to Dr. Ethan Rubinstein, head of adult infectious diseases at the University of Manitoba. 'There are a large number of authors, all of them excellent and credible researchers. And the sample size is very large — 12 or 13 million people taken from the central reporting systems in three provinces.''
