Free-space quantum key distribution transmitter system using WDM filter for channel integration

In this study, we report a transmitter system for free-space quantum key distri-bution (QKD) using the BB84 protocol, which does not require an internal alignment process, by using a wavelength-division multiplexing (WDM) filter and polarization-encoding module. With a custom-made WDM filter, the si...
