Researchers at Rice University have made a groundbreaking discovery in the field of strange metals—materials that defy conventional understanding of electricity and magnetism
Using quantum Fisher information (QFI), a concept borrowed from quantum computing, the team has uncovered how electron entanglement peaks at a quantum critical point, offering a new perspective on these mysterious materials.
The study, led by Qimiao Si, professor of physics and astronomy at Rice, was published on March 14, 2025, in Nature Communications under the title “Amplified multipartite entanglement witnessed in a quantum critical metal.”
Unlike typical metals like copper or gold, strange metals exhibit unpredictable electrical properties, particularly at very low temperatures. Traditional physics fails to explain their behavior. The researchers focused on a theoretical model known as the Kondo lattice, which describes how magnetic moments interact with electrons.
At a critical transition point, these interactions grow so intense that the building blocks of electrical behavior, known as quasiparticles, disappear. Using QFI, the team was able to track how this quasiparticle loss is linked to electron spins becoming highly entangled. The entanglement peaks precisely at the quantum critical point—the boundary between two different states of matter.
Understanding strange metals could have profound technological implications. These materials share properties with high-temperature superconductors, which have the potential to transmit electricity without energy loss. Unlocking their secrets could revolutionize power grids and energy-efficient technologies.
“Our findings reveal that strange metals exhibit a unique entanglement pattern, which offers a new lens to understand their exotic behavior,” said Si. “By leveraging quantum information theory, we are uncovering deep quantum correlations that were previously inaccessible.”
The application of QFI, primarily used in quantum information and precision measurements, marks a novel approach in materials research. The researchers’ calculations aligned with real-world experimental data obtained through inelastic neutron scattering, further validating their findings.
“By integrating quantum information science with condensed matter physics, we are pivoting in a new direction in materials research,” Si explained.
This discovery doesn’t just unravel the mysteries of strange metals; it provides a framework for exploring other complex materials. Enhanced entanglement, as demonstrated in this study, could be a valuable resource for future quantum technologies.
As researchers continue to explore the implications of their findings, the potential applications of strange metals and their connection to superconductors could pave the way for revolutionary advancements in energy transmission and quantum computing.
