In my previous article, I wrote about the exciting world of quantum computing and outlined some of the many benefits that it has the potential to bring to society. However as I alluded to previously, there are still a number of technical challenges that need to be overcome. Today I will try to give brief overviews of two of the most difficult challenges.
The first difficulty is known by many names and covers many related technical challenges, but is usually called
decoherence. A quantum comput...
