It wasn't until 2005 we had the first (probable) qubyte created at the University of Innsbruck in Austria.

You don't need bytes to do computation.

Wouldn't a qubyte be 8 qubits?

The term doesn't make sense because you're not going to use groups of 8 qubits to represent characters on a screen.
We may actually need a new word for 2 qubits (dual-qubits? dubits?) because it seems 2 qubits are enough to break 1-bit of encryption, and I think I've read it's enough to simulate 1 atom, too.

I thought it was x qubits is equal to 2^x classical bits? So wouldn’t 2 “dubits” actually be four times (not twice as) better?
An implementation of quantum computers that is currently flourishing is one that is built out of superconducting circuits. This makes it easier to scale the quantum computer because you can leverage existing nanoelectronic fabrication techniques [1].
