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.

An exotic interplay of electrons

Water that simply will not freeze, no matter how cold it gets — a research group has discovered a quantum state that could be described in this way. Experts have managed to cool a special material to near absolute zero temperature. They found that a central property of atoms — their alignment — did not ‘freeze’, as usual, but remained in a ‘liquid’ state. The new quantum material could serve as a model system to develop novel, highly sensitive quantum sensors.

Entanglement, a special property of nature at the quantum level, is a correlation between two or more objects. A research team recently harnessed entanglement to develop more precise networked quantum sensors. (Image by Brookhaven National Laboratory.)
