Can anyone recommend a few videos, papers, or books that "start at the beginning" for how quantum computing works--the physics parts like entanglement. I'm a computer scientist, so I'm good with the algorithm/programming aspects. Should I start with quantum annealing? Ideally I guess I'd like some pointers to good approachable resources on the ways qubits are made, maintained, written to and read from--start me off at the quantum version of the transistor. Thanks HN.
- cevi 3y agoThis may be a bit on the theoretical side, but it's the best reference for quickly getting up to speed on how quantum computing and entanglement works that I know of: https://cs.uwaterloo.ca/~watrous/QC-notes/QC-notes.pdf https://cs.uwaterloo.ca/~watrous/QC-notes/QC-notes.pdf As for how actual physical qubits are maintained, that topic is tough to find a good explainer for, since every group has a different approach. Some groups use trapped ions, some use two-dimensional quasiparticles, some use spin states of photons... and no one has a clue which approach will be most practical in the end. It's analogous to not knowing whether clockwork or vacuum tubes will be the better way to implement a Turing machine.
