SUMMARY

Topological protection is a critical aspect in extending the lifetime of qubits, particularly in the context of superconducting transmons and photonic qubits. The discussion highlights the importance of isolating qubits from their environment and leveraging topological properties to enhance stability. Key players in this field include Google and IBM, who are actively researching these methods. Understanding the differences between qubit types is essential for applying these techniques effectively.

PREREQUISITES
  • Understanding of qubit types, specifically superconducting transmons and photonic qubits.
  • Familiarity with topological quantum computing concepts.
  • Knowledge of error correction techniques in quantum computing.
  • Basic principles of condensed matter physics.
NEXT STEPS
  • Research topological protection methods in quantum computing.
  • Explore the differences between superconducting transmons and photonic qubits.
  • Learn about error correction techniques specific to quantum systems.
  • Investigate the role of environmental isolation in qubit stability.
USEFUL FOR

Quantum computing researchers, physicists in condensed matter, and engineers working on qubit technology will benefit from this discussion.

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