    I'm familiar with parametric amplifiers. But how do you take a single photon and split it in two (or three...)?

    It happens spontaneously during intense optical interactions with appropriate crystals, given very precise control of direction. Interchange of energy with crystal phonons, etc.

    You add energy. Aitch new, and all that Greek.

    Is that how my green laser pointer works?

    That's second harmonic generation. Basically the same thing backwards.

    Don't have your own Quantum Computer. No worries, Amazon will let you use theirs:

    So every time I get a box from Amazon.... it might contain a Quantum Computer! There is some non-zero probability that it will! But I won't know until I open the box.

    Neither will they!

    You're never sure it's working until you get the electricity bill.

    Quantum computers need electricity? I thought they just worked on the tiny differences between a transcendental number and the closest rational number. Just pour some numbers into the input hopper, and before you know it, other numbers come out the output chute. Just like regular computers, only more expensive. No?

    Researchers at Princeton University have made an important step forward in the quest to build a quantum computer using silicon components, which are prized for their low cost and versatility compared to the hardware in today’s quantum computers. The team showed that a silicon-spin quantum bit (shown in the box) can communicate with another quantum bit located a significant distance away on a computer chip. The feat could enable connections between multiple quantum bits to perform complex calculations. Credit: Felix Borjans, Princeton University

    I bet ATARI will sue them.
