A protocol generates loss-robust crossband entanglement by leveraging intraband entanglement, exceeding direct-transduction limits with performance scaling with input brightness.
(C11) Here the output can be viewed as a tensor product of pure TMSV states with photon numberNS after S and P going through bosonic loss channels of transmissivity γ
