Quantifying the Momentum Correlation between Two Light Beams by Detecting One
Armin Hochrainer, Mayukh Lahiri, Radek Lapkiewicz +2
We report a measurement of the transverse momentum correlation between two photons by detecting only one of them. Our method uses two identical sources in an arrangement, in which…
Interference Fringes Controlled by Non-Interfering Photons
Armin Hochrainer, Mayukh Lahiri, Radek Lapkiewicz +2
We observe spatial fringes in the interference of two beams, which are controlled by a third beam through the phenomenon of induced coherence without induced emission. We show that…
Twin Photon Correlations in Single-Photon Interference
Mayukh Lahiri, Armin Hochrainer, Radek Lapkiewicz +2
We show that it is possible to generate a novel single-photon fringe pattern by using two spatially separated identical bi-photon sources. The fringes are similar to the ones obser…
Entanglement by Path Identity
Mario Krenn, Armin Hochrainer, Mayukh Lahiri +1
Quantum entanglement is one of the most prominent features of quantum mechanics and forms the basis of quantum information technologies. Here we present a novel method for the crea…
