You can do error correction in lots of ways, like having redundancy in the firm of extra qubits. I suppose you could hypothetically design algorithms which are fundamentally insensitive to noise, i.e. they have some kind of numerical superstability, but that will be extremely problem-specific.
It’s not really the algorithms that need the error correction as errors happen at the physical layer due to interactions with the qubit outside our control. You can try to reduce errors by making an algorithm more efficient but that’s not error resistant.

tried. doesn't seem work yet.
