> teleportation might be a reality ;).
Please say "quantum teleportation" instead of "teleportation" so readers don't confuse https://en.wikipedia.org/wiki/Quantum_teleportation with https://en.wikipedia.org/wiki/Teleportation. They are completely different concepts.
> That notion of both “dead and alive” is exactly what superposition is.
No, this is not what superposition is. The cat example was Schrödinger’s method of illustrating how counter-intuitive quantum superposition is. Please refer to the superposition principle (https://en.wikipedia.org/wiki/Superposition_principle) instead.
> But what if you could entangle them together so both would always guarantee to yield the same outcome? That’s what entanglement is all about.
This is not what entanglement is all about. You say "both their wave functions will yield the same outcome." It's the same wave-function when they are entangled, not different ones.
