The development of quantum technology has great scientific significance and strategic value. It is a major disruptive technological innovation that has an impact on and reconstructs the traditional technological system. It will lead a new round of technological revolution and industrial transformation.

For example, quantum computing! The computing power of quantum computers increases explosively with the increase of quantum bits (qubits), forming the so-called "quantum superiority". If quantum computing can be commercialized on a large scale, it will significantly shorten the time required for artificial intelligence applications such as new drug development, code cracking, and search.

The basic principle of quantum computing is to use qubits as the basic unit of information encoding and storage, and to complete the computational task through the controlled evolution of a large number of qubits. Qubits are generally constructed by using quantum in an entangled state, such as two polarization states of a photon, two spin states of an electron, and two energy levels of an ion.

Quantum computers, which is exactly the basic research, black technology, that the world will have in the next two decades; all this, as Jim Clark, the head of Intel, described it: "Quantum computing may be the computing technology of the next 100 years. It's kind of like the space race, once in a generation."

Now, basically, high-tech companies all over the world are carrying out fierce research, competition and snatching!!! In particular, Google, IBM and Intel in the United States are racing to speed up the study of quantum computing in order to take the lead and achieve the so-called "quantum hegemony".

Focus on hot spots

Application Prospect of Diamond in Aerospace Field

The main application of diamond powder

As a kind of super hard abrasive, diamond powder has incomparably superior grinding ability, which has been paid more and more attention by the industrial developed countries. The grinding ability of diamond powder includes the grinding ability of the workpiece and its own wear resistance and crushing resistance, depending on its microhardness, particle size, strength, particle size, and thermal and chemical stability. To sum up, diamond powder used as abrasive has three aspects; (1) Used in the manufacture of resin-bonded tools, metal-bonded tools, and plating tools. (2) for industrial, scientific and medical precision or polishing of various precision components. (3) as a fine abrasive for mold processing, gem polishing processing, gem bearing processing and manufacturing. In addition to the application of diamond powder as a grinding material, another major use is used as a functional material. For example, the use of its thermal properties and electrical properties. By mixing diamond fine powder into thermosetting resin polymer, cellulose, phenolic resin or ceramic sheet, a new material having improved thermal conductivity and reduced thermal expansion can be produced. The diamond powder mixed to the metal sheet, such as sheet or stainless steel sheet can be made with high thermal conductivity, low thermal expansion and light weight of the new sheet material, in the electronics industry can be made into high-density high-energy devices for thermal control. From the form of diamond used as grinding materials, according to the relevant data published figures, the world's industrial consumption of more than 60% of diamond powder is used to make diamond plaster, diamond powder mixture and diamond powder grinding fluid.

Ultra-precision polishing of precision instruments for the use of nanodiamonds

We add nano-diamond to the medium to make nano-diamond polishing liquid, which is now mainly divided into aqueous polishing liquid and oily polishing liquid. Because the nano-diamond polishing liquid nano-diamond particles super hard super hard, with it can remove the material surface small uneven, polished material surface roughness can be reduced to nano-level, so that the material surface finish is very high. At present, nano-diamond polishing liquid can be used in semiconductor silicon wafer polishing, computer head polishing, precision ceramic processing, gem polishing, optical glass polishing and other fields. Nowadays, due to the development of computers, people's requirements for computer storage capacity continue to increase, which makes us want to manufacture larger disks. In recent years, the storage capacity of computer disks has been increasing, but with the increase of storage capacity, the problem is that the gap between the disk and the head is getting smaller and smaller, which is close to 10NM. The surface roughness, scratches and impurity particles of the head and the disk will cause damage to the computer disk. As the distance between the disk and the head has reached the nanometer level, the micron-level polishing liquid has failed to meet the polishing requirements, so only nano diamond polishing liquid can meet the requirements of this aspect. We used nano-diamond polishing liquid to polish the computer magnetic head, and found that the surface smoothness of the magnetic head was greatly improved after polishing. The measured surface roughness at this time was 0.09~0.40nm, while the surface roughness of the magnetic head was 0.45~0.80nm after polishing with ordinary polishing liquid. Compared with nano-diamond polishing liquid, the effect of nano-diamond polishing liquid is much better, thus the quality of the computer magnetic head is also improved, and we can produce more precision, A computer disk with a larger storage capacity. It is worth noting that when polishing, because the computer and other electronic products most avoid corrosion, so be sure to control the pH of the polishing liquid, the study found that the PH value of the polishing liquid is more appropriate to control between 6.5 and 8. Since the content of anions Cl-and SO2-will determine the pH of the polishing solution, the content of Cl-and SO2-should be controlled when preparing the polishing solution for computer head polishing, and the PH value should be observed at the same time.
