By using the temporal correlations of entangled biphotons, measurement performance beyond that of classical techniques is expected to be achieved.The asynchronous optical sampling (ASOPS) method using optical frequency combs enables Joint Temporal Intensity (JTI) measurements with femtosecond resolution by temporally magnifying an ultrafast optical signal into an electrical replica signal and using it as a trigger. In this study, we extended the measurable range for high-precision temporal correlation measurements by further using temporally divided trigger signals as multi-triggers.
