Abstract (in Japanese) (See Japanese page) 
(in English) The position-wavenumber entanglement in entangled photon pairs is the basis for various quantum-optical phenomena.
By using the time-reversal method, the two-photon detection patterns in an entangled two-photon optical system can be reproduced classically.
Here, we report the experiment that first applies the time-reversal method to the quantum-optical phenomena caused by position-wavenumber entangled photon pairs, and classically reproduces the two-photon detection patterns manifesting a focused beam spot beyond the diffraction limit.
