When we are generating a wallet we have seed. The addresses generated against the set of the seed obviously is following a complex algorithm or we would see one address could easily found with another set of seed. I have no idea how the algorithm works and how hard it is. But this is pretty sure that the current computing system we have is not able to decode the algorithm very easily, possiblity is nearly zero. However, what about the future?
Not likely. The reason why quantum computers are perceived to be of a threat against Bitcoin is because of the fact that Shot's algorithm provides an exponential speed up against asymmetric algorithm, specifically ECDSA in Bitcoin's case. This means that the attacker has to have the public key to be able to get to the private key in the first place. It can be mitigated as long as you're able to not reuse address and assuming that the transaction gets confirmed within a reasonable period of time. Again, the running cost of quantum computers likely does not justify the profits from something like this.
Quantum computers also run Grover's algorithm which provides a far lesser speedup for preimage attacks. That isn't very beneficial and would probably not be an area of concern for Bitcoin.
Computer industry is working on quantum computing in fact, in the next 10 to 15 years we may see perhaps thousands even millions times faster computing than the current computing system we have. With a faster computing system the current algorithm could be compromised very easily.
I am sure the developers are aware about this, I am surely not the first one who is thinking about it. I would like to know how we are progressing to face this upcoming advanced speed.
Quantum computers cannot be measured the same way as classical computers. While asymmetric cryptography would probably be compromised given sufficient time, hash functions like SHA256, SHA512, RIPEMD160 could be weakened in due time but it still wouldn't be enough.
