Realization of waveguide many-body quantum optics
Lena M. Hansen, Clara Henke, Christoph Hotter +13
Controlling light photon-by-photon is central to quantum optics. At a fundamental level, photon interactions are mediated by their coupling to atoms, and ultimate control requires…
Testing a continuous-variable Bell-like inequality with a hybrid-encoded system
Yu Meng, Ying Wang, Clara Henke +7
Continuous-variable quantum systems are promising candidates for quantum computing and quantum information processing. It is widely known that quadrature measurements on Gaussian c…
Photon Sorting with a Quantum Emitter
Kasper H. Nielsen, Etienne Corminboeuf, Benedikt Tissot +8
High-quality photonic Bell state measurements (BSMs) enable scalable universal quantum computing and long distance quantum communication. However, when implemented with linear opti…
Directional and correlated optical emission from a waveguide-engineered molecule with local control
Clara Henke, Thomas Wilkens Sandø, Vasiliki Angelopoulou +10
Radiative coupling between quantum emitters leads to a range of spectacular emission phenomena. Dicke studied the foundations of collectively enhanced and suppressed decay, commonl…
High-fidelity entangled photon pairs from a quantum-dot-based single-photon source
Malwina A. Marczak, Spencer J. Johnson, Mark R. Hogg +8
Entangled photon pairs are a ubiquitous resource in quantum technologies, used in quantum key distribution and quantum networking as well as fundamental tests of non-locality. For…
Molecular beam epitaxy of wafer-scale O-band InAs/InGaAs quantum dots on GaAs for quantum photonics
Pavel S. Avdienko, Lukas Hanschke, Quirin Buchinger +13
We report a scalable molecular beam epitaxy strategy to achieve a low density of O-band electrically tunable InAs/InGaAs quantum dots (QDs) on GaAs(001) substrates. Our approach is…
