We've had quantum computers since the 90's. We just haven't had "useful" quantum computers yet [0].
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].

- Xeoncross 9y ago> "We've had quantum computers since the 90's". It wasn't until 2005 we had the first (probable) qubyte created at the University of Innsbruck in Austria.
- kevin_thibedeau 9y agoYou don't need bytes to do computation.
- colejohnson66 9y agoWouldn't a qubyte be 8 qubits?
- mtgx 9y agoThe 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.
- colejohnson66 9y agoI 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?
