Therefore, cracking a Rar file password would take many years with our current technology, but quantum computers running on Majorana Fermion, could crack those passwords in seconds. You see?
No, it won't. That's just silly given no actual evidence aside from shoddy claims and misunderstandings by some video authors. No matter the nonsense that we get from this so-called "particle zoo" that grows every time scientists can't explain an inconsistency, aside from number-theoretic factoring/discrete-log based problems vulnerable to Shor's (for Bitcoin, that is ECDSA), the only viable quantum speedup to general crypto breaking (that is, mining, the 160-bit hash used in addresses, RAR encryption, and so on) is Grover's algorithm, which isn't that much of a speed-up anyway. Please stop regurgitating sensationalist "science" as evidence to wild claims.
