Laser Time Cloak Hides The Fact That An Event Ever Happened

This is the first almost-practical application of temporal cloaking ... but it might work too well. Electrical engineers at Purdue University have found a way to make your data disappear completely--into holes in time. The technique, described in a paper published online in Nature yesterday, uses pulses of light to create "time holes" that allow communication across optic fibers to disappear completely. The idea of a data cloak, a way to hide the transfer of data in "time pockets," has existed f...
