323 00:27:03,440 --&amp;gt; 00:27:07,800 this is actually one of the main problems with building large-scale quantum computers 324 00:27:07,800 --&amp;gt; 00:27:12,000 because it doesn't take just me or you to look at something and make the computer fail, 325 00:27:12,000 --&amp;gt; 00:27:15,360 it can just be some passing electron wandering around, 326 00:27:15,360 --&amp;gt; 00:27:19,400 bounces off this little superconducting loop and says whoa!
