A single flat metalens now handles both excitation and fluorescence collection for diamond quantum sensors, enabling nanoscale sensing in spaces too tight for conventional optics.

My academic path studying physics at Tsinghua University began in 1981 where I completed a Bachelor’s and Master’s before earning a PhD in 1992. I then did a postdoc at the Central Iron & Steel ...

When molecules fall apart, their electric charge doesn't stay put—it rearranges as bonds stretch and break. An international team of scientists has now tracked these ultrafast changes in the small ...

Rydberg atoms are atoms with one or more outer electrons excited to very high energy levels, which interact very strongly with each other. These atoms are widely used to run quantum simulations and ...

Abstract: Inspired by the performance and scalability of autoregressive large language models (LLMs), transformer-based models have seen recent success in the visual domain. This study investigates a ...

Oracle-based quantum algorithms cannot use deep loops because quantum states exist only as mathematical amplitudes in Hilbert space with no physical substrate. Criticall ...

Dr. Andreas Erdmann, head of the Computational Lithography and Optics group at Fraunhofer IISB for decades and SPIE (International Society for Optics and Photonics) Fellow since 2016, has been honored ...

This project aims to develop a computational framework combining computer vision, computer graphics, and machine learning to accelerate and improve the design and simulation of camera lenses.

Abstract: Ray-tracing physical-optics (RT-PO) models have been widely used to simulate array antennas combined with dielectric radomes. In this work, we present an efficient two-dimensional (2D) ...
