Journal ArticleDOI
Narrow band source of transform-limited photon pairs via four-wave mixing in a cold atomic ensemble.
Bharath Srivathsan,Gurpreet Kaur Gulati,Brenda Chng,Gleb Maslennikov,Dzmitry Matsukevich,Christian Kurtsiefer +5 more
TL;DR: Narrow band pairs of time-correlated photons from nondegenerate four-wave mixing in a laser-cooled atomic ensemble of ^{87}Rb using a cascade decay scheme are observed, indicating a transform-limited spectrum of the photon pairs.
Journal ArticleDOI
Generation of an exponentially rising single-photon field from parametric conversion in atoms
Gurpreet Kaur Gulati,Bharath Srivathsan,Brenda Chng,Alessandro Cerè,Dzmitry Matsukevich,Christian Kurtsiefer +5 more
TL;DR: In this article, the temporal envelope of a photon pair source is measured and the authors show that the envelope has a strong antibunching with g(2)(0) < 0.03.
Journal ArticleDOI
Optimized Multi-Ion Cavity Coupling
TL;DR: The results demonstrate that the geometrical configuration of multiple trapped ions can be manipulated to obtain optimal cavity coupling, and presents a new ground for exploring CQED with multiple quantum emitters, enabled by the highly controllable collective light-matter interaction.
Journal ArticleDOI
Reversing the temporal envelope of a heralded single photon using a cavity.
TL;DR: A way to prepare single photons with a temporal envelope that resembles the time reversal of photons from the spontaneous decay process is demonstrated and is expected to be ideal for interacting with two-level systems.
Journal ArticleDOI
Direct measurement of radiation pressure and circulating power inside a passive optical cavity.
Ryan Wagner,Felipe Guzman,Akobuije Chijioke,Gurpreet Kaur Gulati,Matthias Keller,Gordon A. Shaw +5 more
TL;DR: A mechanical force sensor coupled to two optical cavities that provides a pathway to novel nanonewton scale force and milliwatt scale laser power calibrations, enables direct measurement of the circulating power inside an optical cavity, and enhances the sensitivity of radiation pressure-based optical power transfer standards.
