Input-Output Analysis of Quantum Dot SUPER Excitation
Johannes Kerber, Christoph Hotter, Helmut Ritsch +1
The Swing-UP of the quantum EmitteR population (SUPER) two-color pulsed excitation scheme allows for robust and close to 100\% excitation of a two-level quantum emitter using only…
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…
A Quantum Non-Gaussianity Criterion Based on Photon Correlations and
Christoph Hotter, Clara Henke, Cornelis Jacobus van Diepen +2
Quantum non-Gaussian states, which cannot be written as mixtures of Gaussian states, are necessary to achieve a quantum advantage in continuous variable systems. They represent an…
Lieb-Mattis states for robust entangled differential phase sensing
Raphael Kaubruegger, Diego Fallas Padilla, Athreya Shankar +9
We explore a two-node, entanglement-enhanced sensor network for differential phase sensing that exploits decoherence-free subspaces to suppress common-mode noise, a primary limitat…
Quantum Metrology in the Ultrastrong Coupling Regime of Light-Matter Interactions: Leveraging Virtual Excitations without Extracting Them
Christoph Hotter, Adam Miranowicz, Karol Gietka
Virtual excitations, inherent to ultrastrongly coupled light-matter systems, induce measurable modifications in system properties, offering a novel resource for quantum technologie…
Conditional Entanglement Amplification via Non-Hermitian Superradiant Dynamics
Christoph Hotter, Arkadiusz Kosior, Helmut Ritsch +1
Due to the inherently probabilistic nature of quantum mechanics, each experimental realization of a dynamical quantum system may yield a different measurement outcome, especially w…
