Compared with traditional computer chips based on classical mechanics, the biggest advantage of quantum chips is that they have stronger parallel computing ability and faster computing speed. In addition, the communication mode of quantum chips uses quantum superposition state transmission, which has higher security and can achieve functions such as quantum key distribution and quantum teleportation.
Third. Quantum chips are the technical representatives of national development, of which Changdian Technology, Tongfu Micro electricity and Huatian Technology three quantum chips entered the world's top ten, ranking first in the world's continent. The quantum chip is to integrate the quantum circuit on the substrate and then carry the work of quantum information processingI can.
Atomic chip OK. Atomic chips enable high-precision calculations and measurements, and atomic chips enable supercomputing and efficient encryption. Quantum chips cannot achieve high-precision calculation and measurement, and quantum chips cannot achieve supercomputing and efficient encryption.
The difference between photonic chips and traditional electronic chips is that the medium of calculation is different. High-end electronic chips need to use high-precision EUV lithography machines to carve out chip circuits on silicon wafers and integrate tens of billions of transistors. The photonic chip uses light waves as a carrier for information transmission and data computation, so it does not require high precisionLithography machine, China's current level of lithography machine can also meet the basic needs.
1, according to the data provided by Lightmatter, the chip is powered by a milliwatt-level laser light source, and the processor speed using silicon photonics and MEMS technology is 1,000 times faster than the traditional chip, but the power consumption is only one thousand times that of ordinary electronic devices, and is expected to be officially produced in 2021 for commercial use. The main application field is in the future of artificial intelligence AI computing.
