  "abstract": "We propose a synthetic temporal-mode converter (STC) that combines programmable waveform matching with denser time multiplexing for heterogeneous quantum interconnects. Programmable couplers and optical delays reshape known single-photon temporal waveforms through coherent interference between time bins. Conversion to a common single-bin mode concentrates amplitudes from $N$ bins in $\\lceil\\log_2N\\rceil$ mixing stages, simultaneously improving temporal indistinguishability and freeing channel time. Simulations yield mode overlaps above 99.9\\% for exponential and Gaussian inputs. For $N=256$ and $0.5\\,\\mathrm{dB}$ loss per stage, STC gives a 45.6-fold higher photon-pair coincidence rate than temporal gating at equal mode overlap for two exponential inputs. Relative to long pulses, the shortened temporal matched mode can support an approximately 41-fold higher photon-pair coincidence rate when the available time-multiplexing capacity is fully utilized.",
