By utilizing a fiber-based indistinguishable photon-pair source in the 1.55 μm telecommunications band, we present the first, to the best of our knowledge, deterministic quantum splitter based on the principle of time-reversed Hong-Ou-Mandel quantum interference. The deterministically separated identical photons' indistinguishability is then verified by using a conventional Hong-Ou-Mandel quantum interference, which exhibits a near-unity dip visibility of 94±1%, making this quantum splitter useful for various quantum information processing applications.
