Anisotropic nanoscale coherent polariton transport in CrSBr
Paritosh Malik, Dogyun Ko, Vita Solovyeva +11
In a combined experimental and theoretical study, we demonstrate anisotropic polariton transport on the nanoscale in the van der Waals antiferromagnet CrSBr. While effective cavity…
Expressivity of Quantum Reservoir Computers
Nils-Erik Schütte, Niclas Götting, Hauke Müntinga +3
Using Hamiltonian encoding to inject an input into parameterized quantum circuits (PQCs), the output of the PQC can be written as truncated Fourier series. In recent years, the exp…
Effective long-range attraction of moiré excitons under the influence of atomic reconstructions and anisotropic screening
Nils-Erik Schütte, Carl Emil Mørch Nielsen, Niclas Götting +3
The moiré pattern, which emerges due to a relative rotation between two monolayers of transition metal dichalcogenides, features a long lattice period for small twist angles. The…
Memory-Nonlinearity Trade-off across Quantum Reservoir Computing Frameworks
Saud Äindrak, Lara Giebeler, Niclas Götting +2
Quantum reservoir computing (QRC) harnesses driven quantum dynamics for time-series processing, yet the mechanisms behind the differing performance levels across its many implement…
QCSE: A Pretrained Quantum Context-Sensitive Word Embedding for Natural Language Processing
Charles M. Varmantchaonala, Niclas Götting, Nils-Erik Schütte +2
Quantum Natural Language Processing (QNLP) offers a novel approach to encoding and understanding the complexity of natural languages through the power of quantum computation. This…
Electronic localization and optical activity of strain-engineered transition-metal dichalcogenide nanobubbles
Stefan Velja, Alexander Steinhoff, Jannis Krumland +2
Strain-engineered transition-metal dichalcogenide nanobubbles are promising platforms for quantum emission, as revealed by recent experimental observations. In this work, we presen…
