[Invited Talk] Manipulation of entangled photons in time-frequency domain
Ryosuke Shimizu (UEC) PN2019-6
Abstract (in Japanese) (See Japanese page) 
(in English) Time-frequency duality plays a pivotal role in a wide range of modern optics. The conventional one-dimensional (1D) time-frequency duality has been successfully applied to characterize the behavior of classical light, such as ultrafast optical pulses from a laser. However, the 1D treatment is not enough to characterize quantum-mechanical correlations in the time-frequency behavior of multiple photons, such as the biphotons from parametric down-conversion. Two-dimensional (2D) treatment is essentially required, but has not been fully demonstrated yet due to technical problems. Here, we study the 2D time-frequency duality of biphotons, by measuring two-photon distributions in both the frequency and the time domain. It is discovered that the generated biphotons satisfy the Fourier-transform-limited conditions in a two-photon spectral distribution. Our study may pave the way for the quantum-optical synthesizer, the next-generation technology beyond the traditional optical synthesis in the time-frequency domain.
