Microsoft's Quantum Mechanics

Sun, 12/10/2014 - 23:36
New submitter catchblue22 writes MIT Technology Review has an excellent article summarizing the current state of quantum computing. It focuses on the efforts of Microsoft and Alcatel-Lucent's Bell Labs to build stable qubits over the past few years. "In 2012, physicists in the Netherlands announced a discovery in particle physics that started chatter about a Nobel Prize. Inside a tiny rod of semiconductor crystal chilled cooler than outer space, they had caught the first glimpse of a strange particle called the Majorana fermion, finally confirming a prediction made in 1937. It was an advance seemingly unrelated to the challenges of selling office productivity software or competing with Amazon in cloud computing, but Craig Mundie, then heading Microsoft's technology and research strategy, was delighted. The abstruse discovery — partly underwritten by Microsoft — was crucial to a project at the company aimed at making it possible to build immensely powerful computers that crunch data using quantum physics. "It was a pivotal moment," says Mundie. "This research was guiding us toward a way of realizing one of these systems."

Texas Health Worker Tests Positive For Ebola

Sun, 12/10/2014 - 15:22
Thomas Eric Duncan, the first person to have been diagnosed in the U.S. with Ebola, and who subsequently died of the disease, was treated at Texas Health Presbyterian Hospital in Dallas. Now, in a second diagnosis for the U.S, an unidentified health-care worker from the hospital has tested positive for Ebola as well. According to the linked Reuters story, Texas officials did not identify the worker or give any details about the person, but CNN said it was a woman nurse. The worker was wearing full protective gear when in contact with Duncan, Texas Health Resources chief clinical officer Dan Varga told a news conference. "We are very concerned," Varga said. "We don't have a full analysis of all of the care. We are going through that right now." ... The worker was self-monitoring and has not worked during the last two days, Varga said. The worker was taking their own temperature twice a day and, as a result of the monitoring, the worker informed the hospital of a fever and was isolated immediately upon their arrival, the hospital said in a statement. (Also covered by the Associated Press, as carried by the Boston Globe, which notes that "If the preliminary diagnosis is confirmed, it would be the first known case of the disease being contracted or transmitted in the U.S.")
