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 ...

MIT physicists have recreated the most iconic experiment in quantum physics — this time with individual atoms acting as the slits and single photons barely grazing past. Their results have firmly ...

Classical physics theories suggest that when two or more electromagnetic waves interfere destructively (i.e., with their electric fields canceling each other out), they cannot interact with matter. In ...

University of Illinois Physics Professor Paul Kwiat and members of his research group have developed a new tool for precision measurement at the nanometer scale in scenarios where background noise and ...

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 ...

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 ...
