"Physicist proposes a new type of computing at SXSW (South-by-SouthWest Interactive), known as orbital computing. From the article:

A physicist from SLAC who spoke at SXSW interactive has proposed using the state changes in the orbits of electrons as a way to build faster computers. The demand for computing power is constantly rising, but we're heading to the edge of the cliff in terms of increasing performance - both in terms of the physics of cramming more transistors on a chip and in terms of the power consumption. We've covered plenty of different ways that researchers are trying to continue advancing Moore's Law - this idea that the number of transistors (and thus the performance) on a chip doubles every 18 months - especially the far out there efforts that take traditional computer science and electronics and dump them in favor of using magnetic spin, quantum states or probabilistic logic.

A new impossible that might become possible thanks to Joshua Turner, a physicist at the SLAC National Accelerator Laboratory, who has proposed using the orbits of electrons around the nucleus of an atom as a new means to generate the binary states (the charge or lack of a charge that transistors use today to generate zeros and ones) we use in computing."

    Ok, terahertz lasers are to be used as the gate control signal for switching electron orbital states. Fine. What atom-sized engineering primitive creates a terahertz laser beam out of an electron orbital state?

    MOSFETs work well because they are voltage controlled voltage sources. The input and output are of the same "type".

    SIMD single instruction multiple data. I'm guessing the architecture would look really weird, like build 2 to the 32 "devices" and whack them with a single wave of light and the one thats "on" is your answer.

    There's some weird crypto analogy where you build a cracker into Chinese radios and when the light turns on the winner turns the radio in for a huge reward, or something like that.
