Reply to comment by warren_stupidity in can someone explain the difference between quantum computing and classic computing in simpler words? how can quantum computing benefit us from a consumer perspective? by village_aapiser

The largest prime number ever factored by a real quantum computer using Shor's algorithm was 21 back in 2012 so don't hold your breath. In 2019 an attempt was made to factor the number 35 using Shor's algorithm on an IBM Q System One, but the algorithm failed because of accumulating errors. It's tech that sounds great in science fiction but actually building a working quantum computer with enough qbits and low enough noise to do anything useful may be an impossible engineering problem.

right - it might be in the 'fusion reactor' mode of breakthroughs that never actually pan out into something functional. Or not.
