Probing multimode squeezing with correlation functions
Andreas Christ, Kaisa Laiho, Andreas Eckstein +2
Broadband multimode squeezers constitute a powerful quantum resource with promising potential for different applications in quantum information technologies such as information cod…
Probing the negative Wigner function of a pulsed single photon point by point
Kaisa Laiho, Katiuscia N. Cassemiro, David Gross +1
We investigate quantum properties of pulsed light fields point by point in phase space. We probe the negative region of the Wigner function of a single photon generated by the mean…
Accessing the purity of a single photon by the width of the Hong-Ou-Mandel interference
Katiuscia N. Cassemiro, Kaisa Laiho, Christine Silberhorn
We demonstrate a method to determine the spectral purity of single photons. The technique is based on the Hong-Ou-Mandel (HOM) interference between a single photon state and a suit…
A bright, pulsed two-mode squeezer
Andreas Eckstein, Andreas Christ, Peter J. Mosley +1
We report the realization of a bright ultrafast two-mode squeezer based on type II parametric downconversion (PDC) in periodically poled (PP-KTP) waveguides. It…
Purification of Single-photon Entanglement
D. Salart, O. Landry, N. Sangouard +8
Single-photon entanglement is a simple form of entanglement that exists between two spatial modes sharing a single photon. Despite its elementary form, it provides a resource as us…
