Laser &Photonics Reviews, EarlyView.Room‐temperature mid‐infrared (MIR) detectors are demonstrated using lithium niobate surface acoustic wave phononic crystal oscillators integrated with metasurface absorbers. The devices exhibit rapid thermal response and simplified fabrication compared to suspended resonators.

A quantum protocol to win the graph colouring game on all Hadamard graphs
, 2005 This paper deals with graph colouring games, an example of pseudo-telepathy, in which two provers can convince a verifier that a graph $G$ is $c$-colourable where $c$ is less than the chromatic number of the graph.

Global and microlocal aspects of Dirac operators: Propagators and Hadamard states
Mathematische Nachrichten, EarlyView.Abstract We propose a geometric approach to construct the Cauchy evolution operator for the Lorentzian Dirac operator on Cauchy‐compact globally hyperbolic 4‐manifolds. We realize the Cauchy evolution operator as the sum of two invariantly defined oscillatory integrals—the positive and negative Dirac propagators—global in space and in time, with ...

General Gate Teleportation and the Inner Structure of Its Clifford Hierarchies
Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT The quantum gate teleportation mechanism allows for the fault‐tolerant implementation of “Clifford hierarchies” of gates assuming, among other things, a fault‐tolerant implementation of the Pauli gates. We discuss how this method can be extended to assume the fault‐tolerant implementation of any orthogonal unitary basis of operators, in such a

On a New Class of Meromorphic Univalent Function Associated with Dziok_Srivastava Operator
Journal of Kufa for Mathematics and Computer, 2015 In this paper, we introduce and study a new class of meromorphic Univalent functions deï¬ned by Dziok_Srivastava operator for this class. We obtain coefficient inequality, convex set, closure and Hadamard product (or convolution).Further we obtain a(n,δ

Enhancing Lipidomics With High‐Resolution Ion Mobility‐Mass Spectrometry
PROTEOMICS, EarlyView.ABSTRACT Lipids, indispensable yet structurally intricate biomolecules, serve as critical regulators of cellular function and disease progression. Conventional lipidomics, constrained by limited resolution for isomeric and low‐abundance species, has been transformed by ion mobility‐mass spectrometry (IM‐MS).

Ensemble‐based statistical interpolation of atmospheric variables near the surface
Quarterly Journal of the Royal Meteorological Society, EarlyView.This study introduces ensemble statistical interpolation (EnSI), a sequential implementation of ensemble optimal interpolation (EnOI) for spatial analysis of near‐surface atmospheric variables. EnSI extends traditional OI by incorporating a multi‐scale loop, consecutive observation times, and cross‐correlations between variables, providing more ...

Statistical Complexity of Quantum Learning
Advanced Quantum Technologies, EarlyView.The statistical performance of quantum learning is investigated as a function of the number of training data N$N$, and of the number of copies available for each quantum state in the training and testing data sets, respectively S$S$ and V$V$. Indeed, the biggest difference in quantum learning comes from the destructive nature of quantum measurements ...

Open and Closed Loop Approaches for Energy Efficient Quantum Optimal Control
Advanced Quantum Technologies, EarlyView.Concepts from quantum thermodynamics and optimal control are blended to derive a theoretical framework to quantify and minimize the energetic cost of a pulse for unitary synthesis. Two complementary techniques (based on GRAPE and Reinforce‐DRL) are implemented as open‐source software that co‐optimizes the fidelity and energetic cost within quantum ...
