by
Neuroscience News logo for mobile.

Resume: Researchers have developed a new approach to improve uncertainty estimates in machine learning models, increasing prediction accuracy. Their method, IF-COMP, uses the principle of minimum description length to provide more reliable confidence measures for AI decision-making, critical in high-stakes settings like healthcare. This scalable technique can be applied to large models, allowing non-experts to … Read more

New method achieves tenfold increase in quantum coherence time via destructive interference of correlated noise

by

A Bloch sphere of a qubit subjected to cross-correlated noise (blue and red). The method destructively disrupts this noise, resulting in superior performance. Credit: Physical assessment letters (2024). DOI: 10.1103/PhysRevLett.132.223601 Researchers have developed a new method to significantly improve the performance of quantum technology by using the cross-correlation of two noise sources to extend coherence … Read more

‘Motion-picture’ method reveals shape of Milky Way’s dark matter halo

by

In this artist’s impression, the galactic disk warp “dances gracefully” under the torsion of the dark matter halo. Credit: Hou Kaiyuan and Dong Zhanxun of the School of Design, Shanghai Jiao Tong University An international team has developed a “motion-picture” method to measure the precession rate of the Milky Way’s disk curvature. Using a sample … Read more

New method for generating monochromatic light in storage rings

by

A pulsed laser co-propagates with the electron beam through the MLS U125 undulator and imposes an energy modulation. The same undulator serves as a radiator in the subsequent passes of the electron beam. The undulator radiation is detected by a fast photodiode, while the laser pulse is blocked from the detection path using an electro-optical … Read more
