Lasers, devices that emit intense beams of coherent light in specific directions, are widely used in research settings and are central components of various technologies, including optical clocks (i.e., systems that can keep time relying on light waves as opposed to the vibrations of quartz crystals) and gravitational wave detections.Quantum Physics NewsRead More
Efficient generation and reliable distribution of quantum entangled states is crucial for emerging quantum applications, including quantum key distribution (QKDs). However, conventional polarization-based entanglement states are not stable over long fiber networks. While time-bin entanglement offers a promising alternative, it requires complex infrastructure. In this study, researchers explore how stable time-bin entangled states can be
Researchers at the Department of Energy’s Oak Ridge National Laboratory, working with international partners, have uncovered surprising behavior in a specially engineered crystal. Composed of tantalum, tungsten and selenium—elements often studied for their potential in advanced electronics—the crystal demonstrates an unexpected atomic arrangement that hints at novel applications in spin-based electronics and quantum materials.Quantum Physics
