Witnessing quantum entanglement at the macroscale

Conventional wisdom would say no — quantum mechanics washes out in large objects, and we macroscopic beings in the macroscopic world are not privy to the incredible quantum phenomena underpinning everything around us. However, like a lot of conventional wisdom, this is not entirely true. Quantum ‘entanglement’, the definitive essence of quantum mechanics, looms large over the behavior of certain macroscopic objects; objects that you can see with your eyes and hold in your hands. I will describe one of the first papers¹ that demonstrated this, in a fascinating class of materials called ‘quantum magnets’. Incidentally, this influential paper, written in 2006, was coauthored by Anton Zeilinger, who won the <a href="https://www.nobelprize.org/prizes/physics/2022/summary/" rel="noopener ugc nofollow" target="_blank">Nobel Prize in Physics in 2022</a> together with Alain Aspect and John Clauser for his work on quantum entanglement. <a href="https://www.cantorsparadise.com/witnessing-quantum-entanglement-at-the-macroscale-d013796f613d">Read More</a>
