Photonic and electronic state interactions in BaTiO3 based Optical Microcavity [PDF]

open access: yesarXiv, 2021
The photonic modes mediated absorption dynamics at femtosecond time scales along with the control of spontaneous emission tunability are investigated all-dielectric optical microcavity having BaTiO3 (BTO) as defect layer. The cavity-enhanced transient absorption reveals the dominant excited state absorption (ESA) of both photonic and electronic modes ...

Optically heralded microwave photons

open access: yesCLEO 2023, 2023
Interconnecting distant superconducting quantum processors requires optical links. Here, we demonstrate a transducer that generates entangled pairs of microwave and optical photons, achieving a heralding rate of 15 Hz with two added noise photons.

Direct generation of photon triplets using cascaded photon-pair sources [PDF]

open access: yesNature 466, 601-603 (2010), 2010
Non-classical states of light, such as entangled photon pairs and number states, are essential for fundamental tests of quantum mechanics and optical quantum technologies. The most widespread technique for creating these quantum resources is the spontaneous parametric down-conversion (SPDC) of laser light into photon pairs.
