dr. munroe is working on making them larger and longer running. that used to be classical computers were very large in size but very few bits and could not do much but we can do in the 80s with the supercomputer is now on your smartphone. we need to put those resources. >> i would add to that the same technology to build quantum computers is also used for quantum communication is a real-world application and the sensors with those optical technique where you are to navigate your oil that only we can those seemingly fundamental limit that same type of technology is used in computers so i do believe they are the most instructive of all technologies but with that there will be others and quantum communication is optics also with single particles of light approach and then to send data they cannot intercept it. what do with quantum computing? and with those little modules and all this hardware or none of this really exist today i would hang my hat on quantum computing being the most other those technologies. >> and a potential letter to better excepti
