Malware In Quantum Computing?

MattSparkes writes, "Today's quantum computers are not sophisticated enough to do anything malicious to your online bank account; the field is in its infancy. However, there are in theory more ways to attack quantum computers than classical ones. As quantum networking takes off, this is going to become a larger and more immediate problem." The Wikipedia article correctly identifies as an unsolved problem in physics the question of whether it is possible to construct a practical computer that performs calculations on qubits.

No, that's Windows Quantum Advantage: If Redmond observes that your copy of Windows Quantum is not Genuine, a hammer will break a vial of cyanide inside your PC, and your cat will die.

Quantum malware is what your dog installs to introduce sufficient uncertainty in Redmond's WQA check to ensure your cat's demise. (After all, when your cat's momentum is known to be precisely zero, it's gotta be somewhere around your PC.)

You missed the memo, Firefox is immune to Zero Day exploits, but those pesky -1 Day exploits are another story...

And if it's anything like my cat, it almost always will indeed have a momentum of precisely zero.

What you need to learn about quantum computation is a function of what you know. If you know some mathematics, these are good: Kindergarten Quantum Mechanics and A Concise Introduction.... If you don't, I strongly suggest studying linear algebra, at least until you're 100% happy with tensor products of complex vector spaces, learning basic probability theory and then trying the second paper above.
