Data assimilation errors due to incomplete accounting of balanced versus unbalanced moisture

Quarterly Journal of the Royal Meteorological Society, EarlyView.
We investigate data assimilation strategies with moisture and assess the impact of accounting for moisture's balanced and unbalanced components. To illustrate the main ideas, examples are presented using a simple model consisting of linear, moist, shallow‐water equations with stochastic forcing.

Unbiased calculation, evaluation, and calibration of ensemble forecast anomalies

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Standard methods for calculating ensemble forecast anomalies result in statistical inconsistencies between forecast and verification anomalies, even if the underlying forecasts are perfectly reliable. An unbiased evaluation of anomaly‐based ensemble forecasts must account for differences in climatological sampling uncertainty between forecasts and ...

Quantum Nonlinear Spectroscopy via Correlations of Weak Faraday‐Rotation Measurements

Advanced Quantum Technologies, Volume 8, Issue 4, April 2025.
Quantum many‐body systems can have a rich structure of high‐order correlations. Conventional nonlinear spectroscopy can detect only a few types of correlation. A Faraday‐rotation‐based quantum sensing scheme is proposed to extract arbitrary types and orders of correlations, offering a new approach to studying quantum many‐body physics.

Toward Useful Quantum Kernels

Advanced Quantum Technologies, EarlyView.
The hybrid approach to Quantum Supervised Machine Learning is compatible with Noisy Intermediate Scale Quantum (NISQ) devices but hardly useful. Pure quantum kernels requiring fault‐tolerant quantum computers are more promising. Examples are kernels computed by means of the Quantum Fourier Transform (QFT) and kernels defined via the calculation of ...
