Quantum dynamics of optical phonons generated by optical excitation of a quantum dot
Daniel Wigger, Helge Gehring, V. Martin Axt +2
The study of the fundamental properties of phonons is crucial to understand their role in applica- tions in quantum information science, where the active use of phonons is currentl…
Reinforcement Learning Control of Quantum Error Correction
Volodymyr Sivak, Alexis Morvan, Michael Broughton +296
Quantum error correction (QEC) is the primary strategy for protecting a quantum computer from the environment. Its prerequisite is that errors must remain sufficiently rare, which…
Single photon emission from individual nanophotonic-integrated colloidal quantum dots
Alexander Eich, Tobias C. Spiekermann, Helge Gehring +8
Solution processible colloidal quantum dots hold great promise for realizing single-photon sources embedded into scalable quantum technology platforms. However, the high-yield inte…
Scaling waveguide-integrated superconducting nanowire single-photon detector solutions to large numbers of independent optical channels
Matthias HäuÃler, Robin Terhaar, Martin A. Wolff +11
Superconducting nanowire single-photon detectors are an enabling technology for modern quantum information science and are gaining attractiveness for the most demanding photon coun…
Ultra-Broadband plug-and-play photonic circuit packaging with sub-dB loss
Erik Jung, Helge Gehring, Frank Brueckerhoff-Plueckelmann +4
Photonic Integrated Circuits (PICs) offer transformative potential for computing systems, enabling high-bandwidth neuromorphic processors and facilitating low decoherence quantum c…
Quantum-Classical Separation in Bounded-Resource Tasks Arising from Measurement Contextuality
Shashwat Kumar, Eliott Rosenberg, Alejandro Grajales Dau +280
The prevailing view is that quantum phenomena can be harnessed to tackle certain problems beyond the reach of classical approaches. Quantifying this capability as a quantum-classic…
