Circuit-Level Loss Performance of RHG and Foliated Floquet Color Codes in a Compound Photon--Atom Quantum Architecture
This study compared three measurement-based quantum computation codes—RHG, FFCC, and reduced FFCC—using a photon-atom architecture with CZ gates. It found that while RHG has the highest threshold (2.75%), performance ordering reverses when intermodule loss is high. The optimal code depends on the specific operating loss probability and hardware details.
