Scientists at California Polytechnic State University have discovered new forms of quantum matter by varying magnetic fields over time. The breakthrough, detailed in Physical Review B, shows that time-dependent control can produce stable quantum states without static equivalents. This could advance quantum computing by making systems more resistant to errors.

A new analysis indicates that two key quantum computing algorithms for chemistry problems have limited practical use, even with advancing hardware. Researchers suggest that calculating molecular energy levels may not justify the technology's investment as hoped. This challenges the view of quantum chemistry as a major application for quantum computers.

Researchers have created a molecule with a novel topology resembling a half-Möbius strip, requiring four loops to return to the starting point. The structure, made from 13 carbon atoms and two chlorine atoms, was assembled on a gold surface at low temperatures. This discovery highlights potential advances in molecular engineering and quantum simulations.

Researchers at the Norwegian University of Science and Technology believe they have spotted signs of a triplet superconductor in the niobium-rhenium alloy NbRe. This material could transmit both electricity and electron spin without resistance, potentially advancing quantum computing. The finding, if confirmed, might stabilize quantum devices and reduce their energy consumption.
