...said her process will be useful in building highly sensitive optical switches--switches that can be thrown by a single photon...
...most challenging demonstrations for Rueckner lies in the area of quantum mechanics. In the "single photon interference demo," the team sends single photons, one at a time, through slits in a screen. Even though the photons are sent sequentially, students watch the interference patterns as they are projected onto a screen. The result is "completely mind boggling," says Rueckner, but a visual demonstration, rather than a classical explanation, aids the students' understanding...

...string theory you only have one thing; that's the string. [When it] rotates and vibrates in different ways, it can take on the guise of an electron or a quark or a photon," he says. "Everything, in principle, can come out of the string...
...particle has assisted scientists in creating a more unified theory because it consists of a photon-like particle and of an unknown entity, known as the Goldstone Boson...
