The supercomputer of the future operates with quantum bits, but quantum systems are fragile and they degrade easily. Now Danish scientists have managed to turn this degradation into an advantage, making it easier to create the special quantum states required for a quantum computer.
Where should you sit in a roller coaster to get the wildest ride? What is the density of candyfloss? These were some of the challenges at the International Physics Olympiad 2013, which saw contestants testing their skills in Copenhagen’s Tivoli Gardens.
Danish researchers will supply crucial technology for a new mission to find evidence for the Big Bang theory. The mission requires technology that can measure distances of five million kilometres with the precision of a picometre – that's 0,00000000001cm.
