Researchers from Singapore and China have experimentally observed negative entanglement entropy using classical electrical circuits, providing new insights into quantum phenomena without the complexities of true quantum systems. Their work suggests that electrical circuits could serve as a low-cost platform for exploring exotic quantum behaviors, with implications for future quantum technologies. Credit: SciTechDaily.
While usual gapless points that are not geometrically defective i.e. Dirac points possess only eigenvalues within , defective exceptional points also exhibit special isolated EB eigenvalues far outside of . It can be realized by an electric circuit .

In particular, if one sock suddenly becomes inaccessible, one would also lose knowledge of the color of the other sock.
While the theoretical recipe for achieving negative entanglement entropy in a non-Hermitian quantum system has been thought of since a few years ago, actually observing negative entanglement in quantum experiments cannot be easily done. This is due to significant challenges in manipulating intricate quantum states in a way that they gain or lose energy, while at the same time also measuring how entangled they are.
“EB states are special states that provide the key fingerprints for negative entanglement,” said Professor Haiyu Meng from Xiangtan University, co-author of this work. Whenever the host system becomes very sensitive due to the non-Hermiticity, EB states may emerge as a direct consequence of negative entanglement.
