Electrostatic Control Enables Robust Helical Edge Channel Transport in III-V Quantum Spin Hall Insulators
Manuel Meyer, Tobias Fähndrich, Sebastian Schmid +12
Quantum spin Hall transport in InAs/GaInSb-based two-dimensional topological insulators can be limited by parasitic bulk and edge contributions. We demonstrate that these limitatio…
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…
Cascaded Metasurface Interferometer for Multipath Interference with Classical and Quantum Light
Rebecca Aschwanden, Nicolás Claro-RodrÃguez, Ruizhe Zhao +14
Beamsplitters represent fundamental components in both classical and quantum optical systems, enabling the distribution of light, as well as the generation of interference, superpo…
Gate-controlled analog memcapacitance in LaAlO3/SrTiO3 interface-based devices
Soumen Pradhan, Victor Lopez-Richard, Igor Ricardo Filgueira e Silva +8
Current memcapacitor implementations typically demand complex fabrication processes or depend on organic materials exhibiting poor environmental stability and reproducibility. Here…
Hybrid confinement techniques for polariton simulators
Johannes Düreth, Philipp Gagel, David Laibacher +13
Exciton-polariton III-V semiconductor microcavities provide a robust platform for emulating complex Hamiltonians, enabling topological photonics and quantum simulation for advanced…
Enhanced spectral range of strain-induced tuning of quantum dots in circular Bragg grating cavities
Ivan Gamov, Matthias Sauter, Samuel Huber +5
Tunable sources of entangled and single photons are essential for implementing entanglement-based quantum information protocols, as quantum teleportation and entanglement swapping…
