Quantum computing promises it will be the next big thing in the computer world.  There are still many obstacles between the concept of one, and actually creating a useful quantum logic gate or processor, but another step has been taken.  CNET reports on an green paint created in Sweden, circa 1870, that may be a huge step forward in figuring out quantum computing, and spintronics.
“An obscure and unpopular artists’ pigment invented in 18th century Sweden may be the key to a new generation of 21st century electronics.

The pigment, cobalt green, a semitransparent compound made by heating a mixture of zinc oxide and cobalt, has been found to have magnetic qualities that may make it suitable for a whole new family of hitherto impracticable “spintronic” devices based on the inherent magnetic nature of electrons, the researchers claim.”
