Physicists discover novel quantum effect
In a discovery of potentially burning interest to computer and chip manufacturers, physicists at Würzburg University have demonstrated a previous unknown quantum effect - and this could be a big step forward in the development of new, cool computer technologies. The researchers have published their findings in the latest issue of Science, in a joint publication with theoretical physicist from Stanford University ("Quantum Spin Hall Insulator State in HgTe Quantum Wells").
"The techniques that we have recently discovered here in Wuerzburg could alleviate the issue of chips overheating" says Prof. Laurens W. Molenkamp, head of the chair for experimental physics III: "Using the quantum spin Hall effect which we for the first time have demonstrated here, it is possible to transport and manipulate information without energy loss." This means that a future computer could operate extremely fast without losing its cool!
