Selective filtering of multi-photon events from a single-photon emitter
Friedrich Sbresny, Carolin Calcagno, Sang Kyu Kim +8
Single-photon purity is one of the most important key metrics of many quantum states of light. For applications in photonic quantum technologies, e.g. quantum communication and lin…

Dynamically Dressed States of a Quantum Four-Level System
Carolin Calcagno, Friedrich Sbresny, Thomas K. Bracht +8
In this work, we experimentally and theoretically study the dressed-state emission of the biexciton-exciton cascade in a semiconductor quantum dot under pulsed, resonant, two-photo…
