general
Optical quantum chip is a new chip form, which has the advantages that traditional chips cannot reach, but also has the defects that are temporarily inferior to traditional chips.
The most different point between optical quantum chip and traditional chip is that it uses light as a carrier, light instead of electricity, and uses micro and nano processing technology to integrate a large number of optical quantum devices on the chip. Compared with traditional chips, this chip is more integrated, more accurate and more stable, and also has better compatibility.
The limit of an integrated circuit chip is 0.1 nanometers, which is the physical limit of the chip's manufacturing equipment, the lithography machine. But while the nanometer is an accurate unit of measure, the quantum is the smallest known physical unit, a concept mainly used in the microscopic world.
According to the law that the smaller the volume of a single component, the stronger the overall computing power of the chip, on the basis of the traditional semiconductor process, the optical quantum chip that uses the optical quantum effect to achieve efficient computing will far exceed the limit of what the traditional chip can do in terms of performance.
Because the production process is different, the optical quantum chip can be produced without the lithography machine, which also means that the current most advanced 5 nm, 3 nm chip process will no longer be the top chip technology, and the pursuit of smaller nano chips will completely lose significance
i very good
