    Lifetime
In summary, the conversation discusses methods for prolonging the lifetime of a qubit, including error correction, isolation from the environment, and topological protection. The speakers also mention that topological protection is a popular topic in the condensed-matter-physics community and among competitors like Google and IBM. The type of qubit being used can also affect which methods are most effective. One speaker asks for clarification on the concept of topological protection, and the other provides a link for further information.

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

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?
