Moving Ahead Meet the masterminds behind the Toyota Prius and quantum teleportation...
...object like a pen, much less a person," says Gisin. He doesn't rule out, in the far future, the teleportation of a molecule. In the immediate future, there are other applications: last year, for example, a spin-off company of Gisin's lab called ID Quantique developed a quantum key that allows for communication--say, transactions between banks--that is completely inoculated against code-breaking attacks. Because the information is being transported in an unconventional way, it's impossible to track. The technology is being considered by the Geneva canton government for use in e-voting and other programs...
Though the technology appears to straddle the line between science and science fiction, the era of quantum teleportation has arrived. It's not the Star Trek--style beaming up of entire landing parties; the process operates at the subatomic level. What does that mean? Quantum teleportation, in short, is the transmission of characteristics--that is, the quantum state of a particular photon, or particle of light--from one place to another. While it falls short of a capability to beam people or objects to remote locations, it's much more than just sending a fax. The original is destroyed...
...concept of quantum teleportation, first postulated in 1993 by IBM researcher Charles Bennet, has been likened to voodoo. But it is a reality, due in large part to the work of Nicolas Gisin, 52, and his 20 or so graduate students and research assistants at the University of Geneva's Group of Applied Physics. In the basement of the university's old medical-school building, Gisin commands a series of laboratories crisscrossed with laser beams and crowded with the gizmos that make teleportation possible: photon counters, interferometers and plain old mirrors that bounce the lasers around. Last year Gisin...
...looking for something to go beyond it,” Greene says. “I think string theory, in many ways, does exactly what he was hoping. It puts together his own theory, general relativity, with this other framework that is undeniably correct: quantum mechanics...
