...intriguing futuristic application would be processing signals that are carried by individual protons,” says Lukin, who has been on the faculty for three years. “If you could make these single photons interact or ‘talk’ with each other, you could process the signal which is carried by just one single photon. This would allow us to process information in a completely new way and to build new devices like quantum computers...
...idea that anything bigger than a photon can be teleported is fantasy. "It is beyond any foreseeable technology to teleport a physical 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...
...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, but every one of its distinguishing features is re-created elsewhere. Researchers believe...
...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 was able to teleport a photon over four miles...
...know these closet nerds exist, because--improbable as it sounds to those who wish someone would shove a photon torpedo up the Enterprise exhaust--the enterprise still thrives. Though showing its age after 664 TV shows and a 35th birthday last year, the franchise still generates perhaps $200 million a year in revenues when you add up movie grosses, TV ad sales and what's spent on books (500 have been published), DVDs and tchotchkes (Trek ornaments are always among Hallmark's top holiday sellers). Paramount claims merchandise sales have exceeded $4 billion over Trek's lifetime; 470 people have...
