A brotherly research duo has discovered that when the Large Hadron Collider (LHC) produces top quarks – the heaviest known fundamental particles – it regularly creates a property known as magic.

MIT physicists have created a new and long-lasting magnetic state in a material, using only light. In a study appearing today in Nature, the researchers report using a terahertz laser — a light source that oscillates more than a trillion times per second — to directly stimulate atoms in an antiferromagnetic material. The laser’s oscillations are tuned to the natural vibrations among the material’s atoms, in a way that shifts the balance of atomic spins toward a new magnetic state.

EPA grants $1.5 million to four universities, including Stevens, to detect and degrade PFAS ‘forever chemicals’ in soil and water using quantum and materials science techniques.

Zooming in to the “pixels of reality”: the electron microscope helps us to do that. However, it is unsuited for particularly sensitive targets. A Vienna-based research group intends to avoid this problem with a quantum optics trick and thereby set new standards in high-resolution microscopy.

To address these challenges, Tohoku University's Dr. Le Bin Ho led a team that developed a multi-target quantum compilation algorithm. They published their new study in the journal Machine Learning: Science and Technology on December 5, 2024.

Pasqal, a global leader in neutral atom quantum computing, has today announced an ambitious partnership with Riverlane, a frontrunner in quantum error correction (QEC) technology, to accelerate the race towards fault-tolerant quantum computing – a critical milestone, where errors are corrected in real time, for unleashing the full potential of quantum computing.

Though seemingly inevitable, noise in quantum hardware can be tackled by so-called logical qubits – collections of tens, hundreds or even thousands of actual physical qubits that allow the correction of noise-induced errors. Logical qubits are the holy grail of quantum computing, and quantum hardware builder Infleqtion today published groundbreaking work that used the NVIDIA CUDA-Q platform to both design and demonstrate an experiment with two of them.

What’s the best way to precisely manipulate a material’s properties to the desired state? It may be straining the material’s atomic arrangement, according to a team led by researchers at Penn State. The team discovered that “atomic spray painting” of potassium niobate, a material used in advanced electronics, could tune the resulting thin films with exquisite control. The finding, published in Advanced Materials, could drive environmentally friendly advancements in consumer electronics, medical devices and quantum computing, the researchers said.

SandboxAQ today announced a series of scientific and technical milestone publications, collectively marking a set of significant advances in the company’s core research and product development activities. These achievements unlock new methods for biopharma drug discovery as well as development of new materials and battery chemistry.

While atoms are known to wiggle very fast, dopants added to a cuprate superconductor can also cause atoms to meander very slowly. A SLAC study shows this process, called atomic relaxation, offers a new way to explore quantum states in these puzzling materials.
