advantage
1, the optical quantum chip can be completed only by low-end lithography machine, and the processing equipment is not high.
2. Optical quantum chips store information for a longer time.
3, the optical quantum chip has stronger anti-interference to the outside world.
4, optical quantum chip compatibility is better.
5, the control precision of the optical quantum chip is higher.
6. Computers using optical quantum chips can take advantage of existing optical fiber facilities.
drawback
Research and development is very difficult, but also need to solve a lot of problems before practical application.
