What does quantum computing have with bitcoin? First of all quantum computing works on probabilities, so how exactly could that work on an encryption which has specific values? It just guesses it?

Quantum computing will be used for decision making AI, where you can't just calculate the outcome because the number of the variables is too big. If a quantum computer controls a ship on the sea *(in which there are valuables like, some sort of super high tech stem cells which have a low expiration date for example)*,and in front there is a storm; the quantum computer measures the odds between crossing the storm directly and risking the loss of some stem cells or decreasing the speed, or stopping the ship and wait for the storm to pass, in which it risks all the cem stells to expire if the storm lasts longer than expected.
