News: To mask data transferred between a sender and a
receiver, researchers have developed a cloaking device that
creates holes in time and space. Joseph Lukens of Purdue
University in West Lafayette, Indiana, and
colleaguesâmdash;whose
paper
was published online in
Natureâmdash;manipulated the flow of
photons so that minute gaps occurred in the light wave. They
then injected an electrical signal, consisting of binary data,
that went undetected because the data bits passed through the
gaps. Such a device could advance the field of secure
communications by concealing transmissions from potential
eavesdroppers.
