発明の名称 (英語) Quantum entanglement photon-pair producing device and quantum entanglement photon pair producing method
発明の概要(英語) In one embodiment of the present invention, a quantum entangled photon-pair producing device is disclosed which includes a superposed state generating device for generating a superposed state of photon-pairs entering through N (N >= 2) different incident optical paths and being composed of photons having different polarization directions, and a light-guide device for separating the photon-pairs entering through the N (e.g. N is two) incident optical paths into photons having a first polarization direction (e.g. horizontally polarized light) and those having a second polarization direction (e.g. vertically polarized light) and guiding the photons having the first polarization direction and entering through the i-th (1 <= i <= N) (e.g. the first) incident optical path and photons having the second polarization direction and entering through the (N-i+1) (e.g. the second) incident optical path to the i-th (e.g. the first) exit optical path through optical paths having the same optical path length. Therefore, quantum entangled photons of N channels having a quantum correlation with regard to the polarization direction can be produced. With this, a quantum entangled photon-pair producing device capable of producing quantum entangled photon-pairs of multi-channel having a quantum correlation with regard to the polarization direction with high production efficiency is realized.
