New technique uses optical orbital angular momentum lattice to enhance information storage capacity
In the realm of optical holography, the conventional limitations of polarization, wavelength, and incident angle are giving way to a new era of possibilities. A breakthrough technique known as optical orbital angular momentum (OAM) multiplexing has e.....»»
Researchers observe the wave-particle duality of two photons
Understanding the nature of quantum objects' behaviors is the premise for a reasonable description of the quantum world. Depending on whether the interference can be produced or not, the quantum object is endowed with dual features of a wave and a pa.....»»
Discovery of low-lying isomeric states in cesium-136 has applications in particle astrophysics
Large, low-background detectors using xenon as a target medium are widely used in fundamental physics, particularly in experiments searching for dark matter or studying rare decays of atomic nuclei. In these detectors, the weak interaction of a neutr.....»»
"Quantum ping-pong": Two atoms can be made to bounce a single photon back and forth with high precision
Atoms can absorb and reemit light—this is an everyday phenomenon. In most cases, however, an atom emits a light particle in all possible directions—recapturing this photon is, therefore, quite hard......»»
Developing a flat soliton microcomb source
Optical chip-related technology is the inevitable path to retain the validity of Moore's Law, which has become the consensus of academia and industry; it can effectively solve the speed and power consumption problems of electronic chips. This tech is.....»»
