This paper provides a comprehensive overview of spin qubit platforms, detailing their physical implementations, theoretical foundations, and various proposed mechanisms for achieving long-range coupling to enable scalable quantum information processing.
This paper presents a surrogate-accelerated hierarchical Bayesian calibration framework that successfully derives data-informed dissipative particle dynamics models for commercial ultrasound contrast agents by inferring their mechanical parameters from force spectroscopy data across multiple bubble diameters.
This study utilizes TDDFT calculations to demonstrate that while hybrid functionals improve accuracy for short-range excitons in C and PTCDA complexes, the simpler PBE functional outperforms them for long-range charge-transfer excitons, particularly when the exciton radius approaches the screening length.
This paper presents a deep learning-based pipeline using a U-Net CNN to automatically tune 300 mm FDSOI quantum dots by segmenting charge stability diagrams, achieving an 80% success rate in locating the single-charge regime and offering a scalable path toward high-throughput qubit automation.
This paper demonstrates that transient charge dynamics and sublattice oscillations in Su-Schrieffer-Heeger chains serve as real-time signatures capable of distinguishing topologically trivial and nontrivial phases, particularly through the detection of topologically protected edge states.
This paper establishes a direct link between angular momentum conservation in nonlinear optics and the electronic quantum geometry by demonstrating that nonlinear harmonic circular dichroism is proportional to the local Berry curvature, a relationship experimentally verified in an atomically thin semiconductor to enable all-optical control and read-out of this geometric property.
This paper proposes and simulates a novel "leapfrogging" mechanism where mobile spin qubits utilize the valley degree of freedom to shuttle through occupied quantum dots in low valley-splitting regions of silicon, thereby enabling new routing paths and implementing an entangling SWAP two-qubit gate.
This study demonstrates that (101)-oriented RuO₂ thin films, a candidate altermagnet, exhibit giant room-temperature third-order electrical transport responses driven by simultaneous T-odd and T-even quantum geometric quantities, providing a robust method to detect Néel order and a versatile platform for quantum spintronic devices.
This paper introduces a multi-tone spectroscopy method combined with inverse reconstruction to experimentally quantify nonlinear coupling coefficients in nanomechanical resonators, successfully validating the approach by deriving accurate device-specific models for highly tensioned nanostrings that match finite element simulations.
This paper investigates how a single-mode photonic cavity modifies the topological phases of a one-dimensional Su-Schrieffer-Heeger chain in the off-resonant regime by deriving an effective interacting Hamiltonian and validating the resulting phase diagram through consistent agreement between winding number, bulk polarization, and edge correlation function markers.
