Scientists have used large-scale magnetic or chemical reactions to achieve quantum entanglement in solids and liquids at temperatures of minus 270 degrees Celsius. Now, American scientists use a small magnet, so that particles in semiconductor quantum entanglement achieved at room temperature, a new study will help the development of more high-performance quantum devices.
Quantum mechanics is one of the cornerstones of modern physics, and entanglement is one of the strangest phenomena predicted by quantum mechanics experts. Quantum entanglement theory believes that two particles can have “telelectivityâ€â€”in which one particle state change immediately affects the other particle's state, whether they are close at hand or far away. Scientists have proved through numerous experiments that quantum entanglement is true and they are trying to use it to develop future quantum computers, quantum communication networks, and high-precision quantum sensors.
But the head of a new study, the University of Chicago School of Molecular Engineering (established by the University of Chicago and the Aragon National Laboratories of the United States) postgraduate Paul Klimov explained that entanglement is also one of the most elusive phenomena in nature, particles In order to get entangled between them, at first, they must be in a highly ordered state. The macroscopic world looks orderly, but at the atomic scale, it is completely disordered. Therefore, a large number of particles are entangled at the macroscopic scale. It is a very difficult goal.
But now, they use small magnets to entanglement the particles in the semiconductor wafer at room temperature. First, they use infrared lasers to order the magnetic states of thousands of electrons and nuclei, and then use electromagnetic pulses to entangle them. This process makes electrons and nucleuses in semiconductor silicon carbide within a volume of 40 cubic microns. Entanglement has occurred. The study was published in the November 20 issue of the journal Science Advancement.
Osellon, a professor of molecular engineering, said that he can create a stable entangled state in semiconductors at room temperature. Apart from promoting the development of basic physics, he also has significant implications for the development of quantum devices in the future. In the short term, scientists can develop ultra-sensitive quantum sensors. Given that entanglement can be performed at room temperature and silicon carbide is environmentally friendly, such devices can be implanted into living organisms and play a major role in the field of biomedicine. In the long-term, scientists can even entangle particles in distant silicon carbide chips, allowing them to “play their feet†in geostationary satellites and encrypted information communications.
