Scientists Achieve Record-Breaking Entanglement with Magic-Wavelength Tweezers

Quantum entanglement is a remarkable phenomenon where two particles become interconnected, so that the state of one instantly affects the other, no matter how far apart they are. This unique property is a cornerstone of quantum computing and a range of advanced technological applications. While entanglement has been achieved with atoms, achieving it with complex molecules is a significant step forward because molecules offer additional structures and properties, such as vibration and rotation, that can be leveraged in advanced quantum applications.
