The research group, which is formed by three universities in Australia and Finland, develops a key element by silicon. This element is called the single-electron recognizer, which can be used to make the quantum computer. It is able to detect the rotary condition of the single-electron with ninety two percent of fidelity. Many famous experts have joined this research. In order to develop this single-electron recognizer, they use the method of single emission to measure the rotary condition of an electron.

The electron has two opposite nature rotary condition which is actually the ideal description for the qubit. Compared with the traditional bit, the qubit is between zero and one; therefore, the meaning of the qubit will be wider; the speed to process the data will also be improved. What is more, every qubit should be initialized to make quantum computer. The quantum computer, which is based on the silicon, had mentioned by the magazine of nature in the year of 1998. In this system, the qubit is limited by the single phosphorus which is embedded in the silicon chip. Nowadays, new experiments make this idea true. Nobody can make sure the rotary condition of the single-electron before doing the experiment of single emission. Scientists embedded the phosphorus in the silicon, using the new device to detect the rotary condition. These rotary conditions are able to control the current of the surrounding circuit.

Currently, scientists in this group also plan to study the high-speed single-electron. They want to integrate these two different devices. The future goal is to study the interaction between the electric rotation and controlled rotation. Silicon is the main material to make the computer, which will blaze new trails to develop the easier quantum computer. Scientists hope that these new computer can carry out different tasks within least time, such as retrieve data, decode and so on. The related integrated circuit is ST60P.
