Double-heralded single-photon absorption by a single atom

Abstract

We present a single-photon to single-atom interface, where a heralded single photon generated by Spontaneous Parametric Conversion is absorbed by a single trapped ion, subsequently generating a single Raman-scattered photon that heralds the absorption event.

Single Atom – Single Photon Interfaces

Felix Rohde, Carsten Schuck, Markus Hennrich +7 more

In an experimental system of two distant ion traps we trap simultaneously strings of Ca+ ions and observe Hong-Ou-Mandel interference between their scattered photons. We also generate entangled photon pairs whose frequency and bandwidth are matched to an absorption line in the ions, and work towards heralded single photon – single ion interaction.

We demonstrate single trapped ion-single photon interaction by the detection of quantum jumps, strongly correlated with the detection of the quantum-correlated heralding photon. This is a step towards controlling single-photon absorption and transferring photon-to-atom entanglement.

Using spontaneous optical parametric down-conversion, we analyze and experimentally demonstrate heralded generation of shaped single photons, whose modes are losslessly tailored via amplitude modulation on the pump field that drives the down-conversion process.

Towards Heralded Two-Photon Absorption and Two-Photon Excited Fluorescence for Quantum Microscopy and Spectroscopy

Andreas Jechow

The interaction between single or a fixed number of photons with a single absorber is of fundamental interest in quantum technology. The harnessing of light matter interactions at the single particle limit has several potential applications ranging from quantum communication and quantum metrology to quantum imaging. In this letter, a setup for heralded two-photon absorption at the single absorber level is proposed. The setup is based on a heralded two-photon source utilizing spontaneous parametric down-conversion, entanglement swapping and sum frequency generation for joint detection. The feasibility of the scheme is discussed by reviewing recent achievements in utilizing entangled and correlated photons for two-photon absorption as well as single photon absorption experiments at the limit of single absorbers in the context of applications in imaging (here mainly microscopy) and spectroscopy.

For quantum networking, we show high-rate single-mode emission of bandwidth-tunable single photons from a single ion, and heralded absorption by the ion of single photons from SPDC photon pairs. The heralded absorption preserves entanglement.
