Rice University scientists have discovered a first-of-its-kind material, a 3D crystalline metal in which quantum correlations and the geometry of the crystal structure combine to frustrate the movement of electrons and lock them in place.

Researchers at the University of California, Irvine and Los Alamos National Laboratory, publishing in the latest issue of Nature Communications, describe the discovery of a new method that transforms everyday materials like glass into materials scientists can use to make quantum computers.

Two-dimensional quantum materials provide a unique platform for new quantum technologies, because they offer the flexibility of combining different monolayers featuring radically distinct quantum states. Different two-dimensional materials can provide building blocks with features like superconductivity, magnetism, and topological matter. But so far, creating a monolayer of heavy-fermion Kondo matter – a state of matter dominated by quantum entanglement – has eluded scientists. Now, researchers at Aalto University have shown that it’s theoretically possible for heavy-fermion Kondo matter to appear in a monolayer material, and they’ve described the microscopic interactions that produces its unconventional behavior. These findings were published on February 23, 2024 in Nano Letters.

Terra Quantum, a leading quantum technology company, published in Advanced Quantum Technologies journal the first-ever observation of room-temperature superconductivity, Global Room-Temperature Superconductivity in Graphite.

Researchers at the University of California San Diego have used an advanced optical technique to learn more about a quantum material called Ta2NiSe5 (TNS).

Researchers at the Helmholtz-Zentrum Berlin (HZB) have made a significant leap in the field of quantum materials by developing a novel measurement method that accurately detects minuscule temperature differences in the thermal Hall effect. This groundbreaking technique, capable of measuring temperature variations as small as 100 microkelvin, overcomes previous challenges posed by thermal noise, marking a pivotal moment in the study of quantum materials.

Measurement of the non-Hermitian skin effect via iteration for the OBC setup. a, Elements of the initial, randomly generated current vector displayed in polar coordinates for a six-site setup. b, Flow chart of the iterative procedure. c, Final current configuration in the system after 40 iterations. d, Evolution of the phase of each vector element versus the iteration number. e, Evolution of the amplitude of each element versus the iteration number, in units of the largest injected current (150 nA). This final current configuration shows an exponential decay as a function of the lead index, from 6 to 1 (from dark to light blue), which is a direct manifestation of the non-Hermitian skin effect in experiment.
