Using data from the British neutron source ISIS from the year 2000, research teams have now demonstrated the viability of a “quantum entanglement witness” capable of proving the presence of entanglement between magnetic particles, or spins, in a quantum material. A team from HZB led by Prof. Bella Lake was also involved in the analysis.
