Faul-Tolerant Quantum Computing

As of October 2024, tremendous progress has been made on qLDPC code architectures and their logical gate operations.

But there are still some questions I’m curious about, including:

a) qLDPC w/ FBQC integrated photonics?

b) Simpler qLDPC designs based (not too far-fetched) reconfigurable bus + TSVs for superconducting qubits?

c) I’m sort of curious about the routing problem of implementing qLDPC or even just surface code on QCCD ion traps.
