Directional telecom photons from a chirally coupled quantum dot
Kristina Bodiroga, Jacob Ewaniuk, Andrew N. Wakileh +7
Chiral quantum light-matter interfaces, where the internal spin state of a quantum emitter determines the direction in which it emits, are essential building blocks of non-reciproc…
Independent electrical control of two quantum dots coupled through a photonic-crystal waveguide
Xiao-Liu Chu, Camille Papon, Nikolai Bart +5
Efficient light-matter interaction at the single-photon level is of fundamental importance in emerging photonic quantum technology. A fundamental challenge is addressing multiple q…
Sub-radiant states for imperfect quantum emitters coupled by a nanophotonic waveguide
Xiao-Liu Chu, Vasiliki Angelopoulou, Peter Lodahl +1
Coherent interactions between quantum emitters in tailored photonic structures is a fundamental building block for future quantum technologies, but remains challenging to observe i…
An integrated whispering-gallery-mode resonator for solid-state coherent quantum photonics
Arianne Brooks, Xiao-Liu Chu, Zhe Liu +6
Tailored photonic cavities allow enhancing light-matter interaction ultimately to create a fully coherent quantum interface. Here, we report on an integrated microdisk cavity conta…
Lifetimes and quantum efficiencies of quantum dots deterministically positioned in photonic-crystal waveguides
Xiao-Liu Chu, Tommaso Pregnolato, Rüdiger Schott +4
Interfacing single emitters and photonic nanostructures enables modifying their emission properties, such as enhancing individual decay rates or controlling the emission direction.…
Deterministic positioning of nanophotonic waveguides around single self-assembled quantum dots
Tommaso Pregnolato, Xiao-Liu Chu, Tim Schröder +5
The capability to embed self-assembled quantum dots (QDs) at predefined positions in nanophotonic structures is key to the development of complex quantum photonic architectures. He…
A high-fidelity photon gun: intensity-squeezed light from a single molecule
Xiao-Liu Chu, Stephan Götzinger, Vahid Sandoghdar
A two-level atom cannot emit more than one photon at a time. As early as the 1980s, this quantum feature was identified as a gateway to "single-photon sources", where a regular exc…
Experimental realization of an optical antenna for collecting 99% of photons from a quantum emitter
X. -L. Chu, T. J. K. Brenner, X. -W. Chen +4
We present the fabrication and characterization of an optical antenna that converts the dipolar radiation of a quantum emitter to a directional beam with 99% efficiency. Aside from…
