Recently, scientists at the Swiss Federal Institute of Technology (ETH) in Zurich made a step toward building a workingquantum computer byteleporting bits of informationacross a computer chip. The results of the study were detailed Aug. 15 in the journal Nature.
Creating such a circuit is an important milestone, said Benjamin Schumacher, a professor of physics at Kenyon College in Ohio. "Everybody really knows if you are ever going to make a real quantum computer, it must be solid state," said Schumacher, who was not involved in the new research. "Solid state" refers to computers built with single-piece transistors — with no moving parts and with components that are self-contained.
