In their simulated system, image data is first simplified using a process called principal component analysis (PCA), which reduces the amount of information while preserving key features. A complex ...

A team of researchers has demonstrated the ultimate sensitivity allowed by quantum physics in measuring the time delay between two photons. This breakthrough has significant implications for a range ...

(Nanowerk News) In daily life, when two objects are “indistinguishable,” it’s due to an imperfect state of knowledge. As a street magician scrambles the cups and balls, you could, in principle, keep ...

Boson sampling was once considered a problem looking for a solution. Now, it might be the bridge that brings quantum computing to the blockchain. A team of researchers from universities in Australia ...

image: The boson sampling experiments were performed on silica-on-silicon photonic chips. This photo shows such a chip (bottom center) during the fabrication process, where ultraviolet lasers (center) ...

Ars Technica has been separating the signal from the noise for over 25 years. With our unique combination of technical savvy and wide-ranging interest in the technological arts and sciences, Ars is ...

Atoms in an optical lattice perform a "quantum walk" where they experience many different quantum phenomena, such as superposition or tunneling as they move around the lattice. Credit: Alex Downham, ...
