The technology of the voice coil motor (voice coil motor) has been further improved.

Voice coil motor (voice coil motor) small make up reported: journal of science and technology in hefei, June 11 (Reuters) (reporter Wu Changfeng) the reporter learns from the university of science and technology of China, the school professor jian-wei pan and the team cooperation study a model of quantum computation bose sampling robustness for photon losses, prove that tolerate a certain number of photons, the loss of bose sampling can bring improved sampling rate. The research results provide an efficient way to achieve quantum hegemony through bose sampling. In the field of quantum computing, experiments that demonstrate that quantum machines are superior to classical computers in certain problems are called quantum hegemony by the international academic community. In 2010, Aaronson et al. of the Massachusetts institute of technology proposed glassy sampling in theory, and strictly proved that this model is one of the effective ways to realize quantum hegemony. But one of the experimental challenges of bose sampling is the loss of photons. For the first time, pan jianwei and his colleague lu chaoyang explored the glassy sampling of tolerable photon loss in experiments. The researchers developed the highest efficiency and quality quantum dot single photon source in the world, and independently developed the highest transmittance optical quantum circuit integrating 127 beam splitters. Combined with the Shanghai institute of microsystem and information technology YouLiXing team developed high-performance superconducting nanowires single photon detector (SNSPD), experiments show that under the condition of the loss of a certain number of photons, bose sampling still maintain its original computational complexity. At the same time, this new type of glassy sampling can increase the sampling rate exponentially. The research results show that China continues to maintain an international leading level in optical quantum computing and is one step closer to the research goal of quantum hegemony beyond the classical computing ability.

The voice coil motor (voice coil motor) is mainly used in large power of linear motion mechanism, such as automatic door opening and closing device, lifting, transfer and lifting machinery and equipment, drive vehicles, especially for high speed and speed transportation. Because the traction or propulsion can be generated directly, there is no need for intermediate linkage, no friction, no noise, no rotor heat, no centrifugal force. Therefore, its application will be more and more extensive. Because of its superior performance, the voice coil motor (voice coil motor) is used in nc plotter, recorder, nc drawing machine, nc cutting machine, disk memory, precision positioning mechanism and other equipment.
