Today (3 March), the Chinese Academy of Sciences held a press conference for the major achievements in the field of quantum computers, announcing the birth of China's quantum computer of the first Chinese scientists to build the world beyond the early classical computers. Quantum computer refers to the use of quantum coherent superposition principle, in theory, with ultra-fast parallel computing and simulation capabilities of the computer. With the increase of manipulable particles, the computational power of quantum computers grows exponentially, which can provide an effective solution to large-scale computational problems that can not be solved by classical computers and has great potential for development. A quantum computer that manipulates 50 microscopic particles can even handle some specific problems even more powerful than supercomputers. If the speed of a classic computer is now a bicycle, the speed of a quantum computer is like an airplane. By the Chinese University of Science and Technology Pan Jianwei, Lu Chaoyang, Zhu Xiaobo, etc., Zhejiang University Professor Wang Haohua joint research group, recently based on photonics and superconducting quantum computer research has made two major breakthroughs, and today they announced in Shanghai, The World's First Quantum Computer Beyond Early Classic Computers In optical systems, the research team achieved the highest level of 10-photon entanglement in 2016 in the world. This year, on this basis, the world's first single-photon quantum computer capable of surpassing the early classical computers was built using the high-quality quantum dot single photon source developed independently in our country. Recent experimental tests show that the "Bose Sampling" speed of the prototype is at least 24,000 times faster than all similar experiments previously performed by international counterparts than the first ENHAC and TRADIC computer in human history Fast 10-100 times. Light Quantum Lab In the past, quantum computing was faster than classical computers and remained in theory. The prototype took a solid first step towards turning this theory into reality, pushing quantum computers into the realm of competition with classic computers. This is the first time in history to transcend the early classical computer quantum simulator, which laid a solid foundation for the ultimate realization of the quantum computing beyond the classical computing power that the international academic community called "quantum domination." Chinese Academy of Sciences, Professor Pan Jianwei University of Science and Technology to accept an interview In the superconducting system, the research team independently developed a sample of 10-bit superconducting quantum wire. Through the high-precision pulse control and global entanglement operation, successfully achieved the multi-body pure entanglement of the largest number of superconducting quantum bits in the world and passed The tomographic method completely characterizes the 10-bit quantum state. This achievement broke through the record of nine quantum bit manipulations maintained by the United States and formed a complete system of superconducting computers, so that China has also entered the world first-class level in quantum computer research of superconducting systems. According to the plan, the research team of Professor Pan Jianwei from China University of Science and Technology will plan to have about 20 optical quantum bits manipulated and designed, prepared and tested for 20 superconducting qubits by the end of this year. Quantum computers will grow exponentially. PCB/PCBA Separators, also called PCB/PCBA Cutting Machine,PCB/PCBA Cutting Equipment, PCB/PCBA Router Equipment, led Separators etc.

Mainly divided into the following categories:
1. V-CUT splitting machine Advantages: low cost Disadvantages: only straight line splitting. There are burrs.
2. Stamping plate splitting machine Advantages: low initial investment cost and fast speed. Disadvantages: The cost is high in the later period due to the need for special boards and special models. Stressed
3. Milling cutter type board splitting machine Advantages: It can split boards in any shape, with little stress and no burrs on the cutting edge. Disadvantages: the first time cost is higher.
4. Laser splitting machine Advantages: It also has the advantages of a milling cutter type splitting machine, and can perform differential cutting on the PCB board without stress. Disadvantages: The machine is expensive.
