only the person who created it will be able to answer that question.
You can goo to the newbie section and ask there, there are hundred of people who will answer you , from the thousands that know how bitcoin is working.
The coin is basically a bunch of code, everyone knows what and how it works, it's an open book.
There is no secret behind it that only it's creator knows. This isn't Lord of The Rings.
I have read an article about quantum computer . Lots of researchers are working on it and it just moving steps closer to the reality . And if it comes to the reality it will destroy the whole crypto system we use, hence also destroy the bitcoin.
It is not going to destroy bitcoin.
A quantum computer will just have a shot at breaking the privkeys but there are two important things:
1) there is no real quantum computer available and building one capable of that might take a lot of time
2) quantum computers are not magical they too have their limitations so combined with point 1 , it is possible to build a quantum resistant algorithm. There are at least two experimental that have been discussed here, although they are in the same stage as the computers.
