Üblicherweise trägt die Brieftaube die Nachricht stets mit sich; die Information ist an ein physikalisches Objekt gebunden. Der Intuition widersprechend zeigen WissenschafterInnen der Universität Wien unter der Leitung von Philip Walther, der Universität Cambridge und des MIT in einem neuen Kommunikationsprotokoll, dass dies in der Quantenmechanik nicht immer zutrifft. Mit ihrem kürzlich im Fachjournal NPJ Quantum Information publizierten Experiment widerlegen sie damit einen wesentlichen Grundsatz bisheriger Kommunikationsmodelle.(more…)
Forget the scare stories: AI is produced by engineers and its creators have the capability to design it in ways that enhance, rather than hinder, peoples’ lives
“I propose to consider the question, ‘can machines think?’ This should begin with definitions of the meaning of the word ‘machine’ and ‘think’.”(more…)
This year a series of events around the world will celebrate the work of Alan Turing, the father of the modern computer, as the 100th anniversary of his birthday approaches on June 23. In a book chapter that will be published later this year, mathematician Robert Soare, the founding chairman of the University of Chicago’s computer science department, will propose that Turing’s achievement was artistic as well as scientific.
Soare, the Paul Snowden Russell Distinguished Service Professor in Mathematics and Computer Sciences, has played a leading role in computability theory — the field that Turing founded and which is devoted to determining how effectively complex mathematical problems can be solved. In Mathematical Logic in the 20th Century, Gerald Sacks ranked a paper Soare published in the Annals of Mathematics as one of the century’s 31 most important papers in mathematical logic, including computability theory.
