Quantum is not parallel. Quantum is quantum. We did a few quantum gate simulations in my college back in the day. The gist is that entangling bits (say b0, b1, b2, b3 are all entangled), has special properties. You can almost perform retroactive computing. you can send these values to quantum gates to define properties, like b0 + b1 = b2 * b3. Later, you unentangled the values and they will 'snap' into some true state. Like b0,b1,b2,b3 == 1111, but the values 0001 or 0010 are also possible. There is nothing 'parallel' about this. It's just a quantum operator using the properties of entanglement / disentanglement for the purposes of computation. ------- I'd say that quantum is closer to retroactive computing than parallel. Operations seemingly go backwards in time thanks to entanglement. That doesn't mean quantum is useful in all algorithms, but it seemingly has applications in cryptography and 3SAT / NP Complete and... Lol simulations of quantum effects. -------- Ultimately, Quantum is only useful if you get enough bits at a time entangled. For now, it's faster for standard computers to brute-force all 2^32 bit combinations rather than using lasers+diamonds to entangle 32-bits and perform the operations. Quantum needs more entanglement and at lower costs to become competitive. But maybe it happens. At very least, quantum computers do exist but who knows how long it will be before they are competitive.
