Qutrits Bring Quantum Computers Closer 66
KentuckyFC writes "To do anything useful with quantum logic gates, you need dozens to hundreds of them, all joined together. And because of various errors and problems that creep in, that's more or less impossible with today's technology. Now an Australian group has built and tested logic gates that convert qubits into qutrits (three-level quantum states) before processing and then convert them back again. That makes them far more powerful. The group says that a quantum computer that might require 50 conventional quantum logic gates can now be built with just 9 of the new gates. What's more, the gates process photons using nothing more than standard linear optical components (abstract on the physics arxiv)."

Or maybe the cat will be spinning because someone stapled a piece of bread with jam onto the cat's back.

This would have brought many, many more female engineers into the field of computer science (hence accelerating the pace at which computers could do useful things besides transmit, compress, and enhance pornography), except that the same abbreviational logic that turned "binary digit" into "bit" turned "trinary digit" into "tit." This nomenclatural error set computing back nearly three hundred years, and two entire generations of promising computer scientists were lost trying to keep abreast of bad puns.

And a transistor is kind of like a tube. (remember in the 1960s when they replaced all those tube radios with transistor radios?) So really, when it comes right down to it, the Internet IS really a bunch of tubes.
