Abstract

We demonstrate high-speed optical sampling of time-bin qubits through visible-light generation via sum-frequency generation (SFG) using femtosecond laser pulses. The experiment utilizes a periodically poled Mg-doped stoichiometric lithium tantalate (PPMg:SLT) crystal to convert near-infrared signal pulses (1520 nm) and pump pulses (820 nm) into visible light (533 nm). We achieved a conversion efficiency of 10.1% and a temporal resolution of 415 fs, while preserving quantum information, with potential applications in time-gated quantum sensing, LiDAR, and high-precision imaging.
