Symmetrical clock synchronization with time-correlated photon pairs
Jianwei Lee, Lijiong Shen, Alessandro Cerè +3
We demonstrate a point-to-point clock synchronization protocol based on bidirectionally exchanging photons produced in spontaneous parametric down conversion (SPDC). The technique…
Upper bound on the duration of quantum jumps
Mathias A. Seidler, Ricardo Gutiérrez-Jáuregui, Alessandro Cerè +2
We present a method to estimate the time scale of quantum jumps from the time correlation of photon pairs generated from a cascade decay in an atomic system, and realize it experim…
Multi-pulse fitting of Transition Edge Sensor signals from a near-infrared continuous-wave source
Jianwei Lee, Lijiong Shen, Alessandro Cerè +4
Transition-edge sensors (TES) are photon-number resolving calorimetric spectrometers with near unit efficiency. Their recovery time, which is on the order of microseconds, limits t…
Transmission spectroscopy of a single atom in the presence of tensor light shifts
Matthias Steiner, Yue-Sum Chin, Christian Kurtsiefer
We investigate the interplay between Zeeman and light shifts in the transmission spectrum of an optically trapped, spin-polarized Rubidium atom. The spectral shape of the transmiss…
Operating a near-concentric cavity at the last stable resonance
Chi Huan Nguyen, Adrian Nugraha Utama, Nick Lewty +1
Near-concentric optical cavities of spherical mirrors can provide technical advantages over the conventional near-planar cavities in applications requiring strong atom-light intera…
Characterization of a photon pair source based on a cold atomic ensemble using a cascade level scheme
Alessandro Cerè, Bharath Srivathsan, Gurpreet Kaur Gulati +2
We characterize a source of photon pairs based on cascade decay in a cold Rb-87 ensemble. This source is particularly suited to generate of photons for interaction with Rb-87 based…
