A long-standing bottleneck in photonic quantum technology may finally be easing. Researchers in Germany ...

A team of researchers from the University of Stuttgart and the Julius-Maximilians-Universität Würzburg led by Prof. Stefanie Barz (University of Stuttgart) has demonstrated a source of single photons ...

A century-old thought experiment on wave–particle duality is brought into the laboratory using a single trapped atom ...

A research team led by Prof. XUE Xianghui from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) proposed a wind sensing lidar theory based on ...

Perhaps one of the most famous experiments in physics has been giving us the wrong message all these years. For nearly two centuries, the double-slit experiment has been providing a direct visual ...

Laser spectroscopy is a powerful tool for atmospheric gas analysis, yet traditional methods face challenges due to atmospheric turbulence and significant energy loss. While dual-comb spectroscopy ...

Two-photon absorption and quantum light spectroscopy have emerged as transformative tools in modern optical research. At the heart of these techniques is the simultaneous absorption of two photons to ...
