Physicists unlock way to measure quantum entanglement inside real-world materials
SMRTR summary
Researchers have developed a groundbreaking technique that can directly measure quantum entanglement inside real-world materials for the first time, solving a long-standing problem in quantum physics. The method combines traditional neutron scattering with quantum Fisher information to create an "entanglement meter" that works even with imperfect materials. Testing on well-understood magnetic crystals showed remarkably close matches between experimental results and theoretical predictions, potentially transforming how scientists explore quantum materials for future quantum computers and communication networks.
