At the University of New South Wales, scientists have created the first single-atom transistor using a repeatable and reliable technique. The scientist used a scanning-tunneling microscope (STM) to manipulate hydrogen atoms around a phosphorus atom on a silicon wafer inside a vacuum chamber. This tiny transistor can one day become a building part of a quantum computer. According to Moore's law, which states that the number of transistors that can be placed inexpensively in an integrated circuit, predicts that this technology will reach the market by 2020. Can this law hold for quantum computers?
