A true quantum computer can perform the calculations a normal computer does in fractions of the time. For instance, you could run a program to solve for the asymmetric cryptography keys for a Bitcoin (hacking ownership of the Bitcoin) that could take years to complete on a modern computer. A quantum computer is so much faster it could do this in fractions of a second. The digital cryptographic cybersecurity solutions used for banking and stock market accounts would also be similarly at risk of being made obsolete in fractions of a second. Luckily, true quantum computers as they exist now are only functional for maybe seconds at a time in isolated development sandboxes as they are only operational at -273 Celsius and below. It's not a technology that could make it to being a household device, probably, ever.

"-273 Celsius and below"

Wait, isn't that Absolute Zero? How can there be temperatures lower than that?

Absolute zero is -273.15C, which is frequently rounded to -273C for popular consumption. However, that 0.15C is like a buffer the size of an ocean to a scientist.

Huh, interesting. That makes sense though!

Now you're understanding the real problem with the technology EVER becoming operational at any practical level.

Time to break the laws of thermodynamics!
