Here's a simple explanation of quantum bits that is totally true, but unfortunately doesn't provide much intuition, or help you understand why quantum is faster than classical: A quantum bit is a pair of real numbers (let's call them a and b) such that a2 + b2 = 1. That's it. The simple and somewhat unsatisfying fact is that normal intuition doesn't really apply to quantum computing.
Here's a fantastic video that explains how a quantum bit leads to quantum speedup, entanglement, and quantum teleportation using the math.
I know less about quantum computer hardware, but your hardware difficulty explanation seems on point.
No worries, and thanks for your original comment. I think it's great to talk about common misunderstandings, that way everyone comes out with a better understanding.

Although this "ternary" explanation is simple and seems to provide some intuition about why a quantum computer is faster, it's incorrect. Quantum bits are fundamentally different from binary and ternary bits.
Ternary bits are actually possible in classical computers. Ternary bits are (almost) never used because reliable binary bit hardware was developed first.
Some people have built ternary computers which are super cool though!.

I certainly had picked up some incorrect information, then. Thanks for the insight!
