Bayesian and Markovian classical feedforward for discriminating amplitude damping channels [PDF]

open access: yesarXiv
We address the issue of multishot discrimination between two qubit-amplitude damping channels by invoking a simple adaptive protocol that employs Helstrom measurement at each step and classical information feedforward. We contrast the performance of Bayesian and Markovian strategies.

Photopolymerization‐Induced Phase Separation in (Meth)Acrylate‐Based Photopolymers From a Characterization Point of View

open access: yesJournal of Applied Polymer Science, EarlyView.
ABSTRACT This work investigates the development of photopolymerization‐induced phase separation (PhIPS) in methacrylate‐based photopolymers. Bisphenol A ethoxylated dimethacrylate (BisEMA) was copolymerized with urethane‐based diacrylate diluted in isobornyl acrylate (UI) under UV irradiation, using diphenyl‐(2,4,6‐trimethylbenzoyl) phosphine oxide ...

Ultrafast Demagnetization Through Femtosecond Generation of Non‐Thermal Magnons

open access: yesAdvanced Physics Research, EarlyView.
A fully ab initio parametrized model is developed to describe out‐of‐equilibrium magnon dynamics in ferromagnetic metals. Applying this model to ultrafast laser‐induced demagnetization, it is revealed that the generation of non‐thermal magnons provides a sizable demagnetization within 200 fs in excellent comparison with experiments, which establishes ...

Mechanical Spin Waves in a Nonlocal Discrete Magnetoelastic Lattice with Negative Group Velocity

open access: yesAdvanced Physics Research, EarlyView.
A discrete magnetoelastic lattice enables mechanical spin waves. The zigzag‐arranged lattice consists of repulsive magnets. The top and bottom rows of the zigzag lattice show opposite spin directions. These spin waves arise due to the coupling between longitudinal and transverse motions.

Enhancing Signal Purity in Josephson Structure Measurements

open access: yesAdvanced Physics Research, EarlyView.
A low‐noise signal measurement system for dilution refrigerators is presented, combining multistage cryogenic filtering and electromagnetic shielding to suppress broad‐spectrum noise. The setup enables sub‐nanoampere switching current measurements in Josephson junctions, surpassing commercial systems.

Testing Protocols for Obtaining Reliable Pair Distribution Functions from Laboratory X‐Ray Sources Using PDFgetX3

open access: yesChemistry–Methods, EarlyView.
This work explores data acquisition and reduction protocols for atomic pair distribution scheme that enhances high‐angle data collection, and the effects of instrumental parameters on resulting pair distribution functions are examined. A correction for sample absorption in PDFgetX3 is introduced. Herein, data acquisition protocols are explored and data

Capacitance Measurements for Evaluating Electrochemical Double‐Layer Models and Potentials of Zero Charge: A Reassessment

open access: yesChemPhysChem, EarlyView.
The electrochemical currents of oxide formation, hydrogen evolution reaction, and oxygen reduction reaction are shown to affect the potential dependencies of measured capacitances. Based on these findings, the routine approach of evaluating models for the electrochemical double layer and determining potentials of zero charge by capacitance measurements
