The only barriers to them working are engineering challenges which may prove insurmountable, may not. There are not any theoretical considerations that would make them not work.
- ericpauley 5y agoThere are certainly possible reasons why quantum computing could be impossible. To me the most compelling of these would be that the error rate of physical qubits might fundamentally always exceed the threshold for correction with any real ECC as the number of logical qubits increases. I highly recommend reading [1] for an overview of the various skeptical viewpoints on quantum computing. Note that, while Aaronson argues most of the initial arguments are trivially wrong, he admits that whether or not error correction is fundamentally impossible is an open question.

- Jensson 5y agoTrying to build a quantum computer is probably a good way to learn more about quantum interactions, since it would stress those to its limits to work.
- Azsy 5y agoI've always seen it the other way around. We can keep solving the engineering challenges, but the universe might simply not allow us to get a return on investment with every additional qubit.
- stephc_int13 5y agoWe can also consider Alcubierre drive to be an engineering problem, don't you think?
- tsimionescu 5y agoNot really, the Alcubierre drive depends on things we have no reason to think exist in the universe (negative energy). It's also likely that the Alcubierre drive doesn't actually allow accelerating from slower than light speeds to higher than light speeds. QC in contrast must exist or else QM is fundamentally wrong - not incomplete, but wrong.
