A brief introduction to quantum computing

Re:A brief introduction to quantum computing by ianai on Sunday June 03, 2018 @02:49AM (#17218284)

i once read about a theory of matter where under the right circumstances a larger system of quantum particles may act in a way consistent to a system composed of fewer particles. The larger solution approaches an exchange of, say, one electron or photon when really it’s an exchange of many particles. Does anyone know the name for that area of study?

To answer my own question: quasiparticles

I can’t help but think that may be a more tractable QC construction.

Unfortunately, things are quite a bit more complicated than this. The current issues in quantum computing aren't so much that it becomes difficult to describe a many-qubit system, but that those qubits individually (and pair-wise) aren't well controlled, and we just aren't good at coming up with many algorithms given these constraints.

Yes, and I’m wondering whether the current qubits are too fragile. Like whether there’s a way to construct a qubit out of a more naturally rebalancing system - somewhat analogous to an acid base buffer.
