Research teams from USTC have realized a high-performance single-photon source with an efficiency beyond the scalable linear optical quantum computing loss tolerance threshold for the first time.

In situ diagnosis Multiphoton microscopy combines second- and third-harmonic generation (SHG and THG), along with two- and three-photon excitation, to rapidly visualize molecular and structural ...

The topics covered are Feynman diagram rules, microscopic mean-field theories (Hartree-Fock and Kohn-Sham theories, natural orbitals), many-body perturbation theory, large-scale diagonalization ...

RR is a generator of syntax diagrams, also known as railroad diagrams. It is a self-contained tool with both a browser-based GUI and a batch mode. Besides generating diagrams from EBNF rules, RR also ...

The measurements showed that the absorption corresponds to single photon traveling in either one or another beam. The results of our measurements and of single photon interference experiments, ...

We also learned an upcoming GPU family, due to arrive in 2028, will be named after Richard Feynman. Surely you're joking! It's not that unusual for chipmakers to tease their roadmaps from time to time ...

Surface waters in the Southern Ocean have been cooling in recent decades, contrary to the warming predicted by climate models. Researchers have now measured how much of this unexpected cooling since ...

China's flagship synchrotron radiation facility, the High Energy Photon Source, has entered its final construction stage as it began the joint-commissioning phase, the Institute of High Energy ...

Get Instant Summarized Text (Gist) A novel protocol enables photon entanglement without quantum measurement, potentially transforming photonics-based quantum computing. This method uses non ...

Robert P Crease visits the High Energy Photon Source near Beijing, which will be – when it opens later this year – the most advanced fourth-generation synchrotron-light source Leading light The High ...
