Photo: VCG China’s first MLLAS-100 laser annealer dedicated to quantum chip production has been successfully developed, a move aimed at solving instability and increasing production quality when the number of quantum bits increase, according to Chinese media reports. Functioning as a “scalpel”, the MLLAS-100 laser annealer can accurately remove “defects” in quantum chips and enhance chips performance when expanding to multiple bits, stdaily.com reported on Wednesday. The laser annealer is independently researched and developed by Origin Quantum Computing Technology Co based in Hefei, East China’s Anhui Province, and can reach a hundred nanometer ultra-high positioning accuracy in a bid to achieve the laser annealing in a single quantum bit. The laser anneal technique can directionally control the frequency parameters of modified quantum bits, and solve the problem of qubit frequency crowding in multi-bit expansion. The laser annealer is like a “scalpel” for a doctor performing surgery, which can be used to improve the production quality of quantum chips by solving targeted problems following issues detected by the nondestructive probe electrical measurement platform, said Jia Zhilong, deputy director of Anhui Quantum Computing Engineering Research Center. Named NDPT-100, China’s first nondestructive probe electrical measurement platform was launched by Origin Quantum in December, which will be used in production of chips for quantum computers. It can realize fast and accurate measurement of quantum bit resistance, identify the quality of quantum chips with almost zero damage, according to the report. Just like the lithography machine is a basic industrial machine for the manufacturing of traditional chips, the instrument is one of the most important industrial machines for quantum chip manufacturing, which will significantly shorten the R&D cycle of quantum chips while improving quality, Jia said in a […]
