I Can Topological Protection Extend the Lifetime of a Qubit?

[Emrissa]

Hi everyone,
Besides error correction, what other aspects can we do to prolong a qubit's lifetime?

Isolation from environment, topological protection, ...

The latter seems to be a very hot topic in the condensed-matter-physics community and at Google as well as IBM as competitors :-).

In practice, it very much depends on the type of qubit you are using; a photonic qubit is very different from a superconducting transmon.
I think you need to be more specific,

Hi...
What do you mean by topological protection?

Collapsing/ Moding/Quotienting out Braids into Knots. Topology gives, describes global properties, while geometry is local, if I may be overly vague.
