Creating different kinds of light with manipulable quantum properties

Science Daily  September 27, 2019
An international team of researchers (Louisiana State University, NIST, Mexico, Germany) experimentally demonstrated that the manipulation of the quantum electromagnetic fluctuations of two-mode squeezed vacuum states leads to a family of quantum-correlated multiphoton states with tunable mean photon numbers and degree of correlation. The technique relies on the use of conditional measurements to engineer the excitation mode of the field through the simultaneous subtraction of photons from two-mode squeezed vacuum states. They demonstrated the engineering of a quantum state of light with up to ten photons which is an important step towards the generation of entangled lasers. The research has quantum technology applications in imaging, simulation, metrology, computation, communication, and cryptography, among other areas…read more. Open Access TECHNICAL ARTICLE
