One potential application: Enhancing the sensitivity of atomic magnetometers used to measure the alpha waves emitted by the human brain. Scientists are increasingly seeking to discover more about quantum entanglement, which occurs when two or more systems are created or interact in such a manner
Researchers using an optical parametric oscillator light source succeeded in producing two entangled light beams.
Scientists are increasingly seeking to discover more about quantum entanglement, which occurs when two or more systems are created or interact in such a manner that the quantum states of some cannot be described independently of the quantum states of the others. The systems are correlated, even when they are separated by a large distance. Interest in studying this kind of phenomenon is due to the significant potential for applications in encryption, communications, and.
However, this was not sufficient to show the beams were entangled. In addition to the intensity, the beams’ phases, which have to do with lightwave synchronization, also needed to display quantum correlations. “That’s precisely what we achieved in the new study reported in,” he said. “We repeated the same experiment but added new detection steps that enabled us to measure the quantum correlations in the amplitudes and phases of the fields generated.
Enhancing the sensitivity of atomic magnetometers used to measure the alpha waves emitted by the human brain is one of the potential applications, he added.

Innovation strengthens electron-triggered light emissions for quantum-based computational and communications systemsThe way electrons interact with photons of light is a vital part of many modern technologies, from lasers to solar panels to LEDs. But the interaction is inherently weak because of a major mismatch in scale: the wavelength of visible light is about 1,000 times larger than an electron, so the way the two things affect each other is limited by that disparity.
