Chinese company launches new laser annealer to improve quantum chips quality

Media reports indicate that Chinese engineers have developed the country’s first MLLAS-100 laser annealer, which will help solve instability and increase production quality when the number of quantum bits increases. The laser annealer is able to accurately remove defects in quantum chips and enhance chips’ performance when expanding to multiple bits.

Origin Quantum Computing Technology, based in Hefei, East China’s Anhui Province, developed the device. This can reach 100 nanometer ultra-high positioning accuracy to achieve the laser annealing in a single qubit. The device can be compared to a surgical device for accurately removing defects in quantum chips and enhance chips performance.
