In this episode of the Physics World Weekly podcast, we’re focussing on quantum physics and the contentious idea of cold fusion. First up, Anna Demming reports on her trip to the House of Commons in London, where she attended a special event about Quantum Technologies in Oxfordshire. Later in the show, we bring a discussion of some of the other research highlights making the headlines this week. That includes the news that Google and several research institutes in North America have reopened what they call the “cold case” of cold fusion. Despite the many failures to observe cold fusion, the scientists maintain that the case is not yet closed.
