According to the US Daily Science website on July 27th, American scientists successfully manufactured ultrapure gallium arsenide and allowed it to exhibit a special state in which electrons no longer obey the physics of single particles. The rules of learning are governed by the interaction between them (explained by the laws of quantum mechanics), and this ultrapure material and state are expected to be used in the study of high-speed quantum computers.
Quantum computers use electronic quantum mechanics to store and process information. Compared with traditional computers, they are more powerful and efficient. This requires the electrons to be in an interconnected state, and an electronic change will be immediately reflected by other electrons. If scientists can control these processes, they can use it to create parallel processing to perform calculations that classic computers cannot.
Michael Montura, an associate professor of physics at Purdue University in the United States, points out that in order to capture the electrons in the microscope and force them to interact only, the material must be very pure. Any impurity can cause electrons to scatter and destroy this fragile state of association. . At the same time, scientists must also cool the electrons to a fairly low temperature and apply a magnetic field to bring it to this state of association.
The team led by Monfil engineered and manufactured a device called the high mobility gallium arsenide molecular beam epitaxy (MBE) system. The ultra-pure gallium arsenide semiconductor produced by this device achieves an atomic level of precision. A perfectly aligned lattice composed of helium atoms and arsenic atoms can capture electrons in a two-dimensional plane, preventing electrons from moving up and down, and limiting their ability to move forward and backward and left and right.
The research participant, physics associate professor Garbo Casey, used the laboratory's special equipment to cool this material and electrons to 5 milli-Kelvin (nearly absolute zero). Casey explained: "At room temperature, electrons are like billiard balls that collide with each other, obeying the laws of classical mechanics. With decreasing temperatures, electrons will calm down and realize the advent of nearby electrons. Then, electrons may collectively Act, and this collective behavior is in accordance with the laws of quantum mechanics." He said that electrons are engaged in a complex "dance", they are trying to present the best arrangement, let it reach the lowest energy level and eventually form a new The mode or ground state.
Munfrra pointed out: "These singular states go beyond the standard model of solid physics, and we know little about it. Most of the standard materials do not exist in these states. They only appear in the state of ultra-pure gallium arsenide semiconductor crystals. Next, the latest research provides us with a new perspective for understanding basic physics."
Manfrella said: "If we can use this kind of electronic behavior in semiconductors, it is also a viable way to build quantum computers. Of course, this work is still in its infancy, and we still have a long way to go. However, the latest research gives us the opportunity for the first time to take a glance at physics and new particles that are not understood."
