In a paper titled “Multiphoton quantum-state engineering using conditional measurements“, researchers at the Louisiana State University (LSU) describe a quantum manipulation and control of light, which might have applications in imaging, simulation, metrology, computation, communication, and cryptography.
Magaña-Loaiza’s team successfully demonstrated a method to generate groups of photons with these same powerful properties, aka multiphoton states, and managed to build a single source to produce multiphoton packets that share similarities with entangled lasers. Most impressively, it can generate multiple kinds of light with manipulable quantum states in one single setup. In addition to generating single photons, the team can also produce entangled laser light and entangled natural light with desired properties. (Louisiana State University)
