Advanced Quantum Technologies, EarlyView.Light–pulse atom interferometry with ultra‐cold quantum gases is proposed and numerically benchmarked as a competitive platform to test the modulo‐square hypothesis of Born's rule. The interferometric protocol utilizes a combination of double Bragg and single Raman diffraction pulses to induce multipath interference in Bose–Einstein condensates and ...

Quantum simulation of the one-dimensional Fermi-Hubbard model as a Z_{2} lattice-gauge theory
Physical Review ResearchThe Fermi-Hubbard model is one of the central paradigms in the physics of strongly correlated quantum many-body systems. Here we propose a quantum circuit algorithm based on the Z_{2} lattice gauge theory (LGT) representation of the one-dimensional Fermi-

Efficient Simulation of Open Quantum Systems on NISQ Trapped‐Ion Hardware
Advanced Quantum Technologies, EarlyView.Open quantum systems exhibit rich dynamics that can be simulated efficiently on quantum computers, allowing us to learn more about their behavior. This work applies a new method to simulate certain open quantum systems on noisy trapped‐ion quantum hardware.

Anomalies of non-invertible symmetries in (3+1)d
SciPost PhysicsAnomalies of global symmetries are important tools for understanding the dynamics of quantum systems. We investigate anomalies of non-invertible symmetries in 3+1d using 4+1d bulk topological quantum field theories given by Abelian two-form gauge ...

Small Science, EarlyView.By controlling the Cr intercalant (δ) in Cr1+δTe2, the topological Hall effect (THE) amplitude (ρTHEpeak$\rho_{\text{THE}}^{\text{peak}}$) and Dzyaloshinskii–Moriya interaction strength can be tuned, revealing a strong correlation between them. Moreover, the largest ρTHEpeak$\rho_{\text{THE}}^{\text{peak}}$ of 2.75 μΩ⋅cm$2.75 \text{ &amp ...

SusMat, EarlyView.An S‐scheme In2O3/TiO2 heterojunction photocatalyst is developed for efficient CO2‐to‐CH4 conversion, achieving a CH4 production rate of 64.1 µmol g−1 h−1 with 96.0% electron selectivity. Combined DFT and DRIFTS analyses reveal significantly enhanced charge separation, improved CO2 activation, and stabilized intermediates in the heterojunction ...

Noise-Aware Variational Eigensolvers: A Dissipative Route for Lattice Gauge Theories
PRX QuantumWe propose a novel variational ansatz for the ground-state preparation of the Z_{2} lattice gauge theory (LGT) in quantum simulators. It combines dissipative and unitary operations in a completely deterministic scheme with a circuit depth that does not ...

Dynamic Bismuth Clusters in an Ionic Conducting Copper Iodide Matrix
Zeitschrift für anorganische und allgemeine Chemie, EarlyView.The cubic room‐temperature structure of (Bi9)[Cu8I13] shows dynamic effects that involve fluctuations in bonding within the (Bi9)5+ polycation and mobility of the Cu+ cations. Flash freezing results in a fully ordered, polar monoclinic structure, which can be interpreted as a hierarchical filling variant of the NaZn13 structure type.
