The quantum world can be on or off at the same time. The way I see it our current internet uses (0) or (1), on or off, up or down, yin or yang, all computing has been restricted by this one single command. Should my “state” be positive or negative? In our current computing world we are confined by the need of the command. In the quantum state there is no need for the command because the quantum particle exists as both at the same time. Thus, the gillions and gillions of commands needed for functionality can be eliminated.
The new light-based quantum computer made by China has achieved quantum supremacy.
The name of the computer is called Jiuzhang. It can perform a calculation in 90 seconds that would take the fastest super computer over a half billion years.
