Kagome Superconductor Defies Time Reversal at Extreme Cold

Researchers at the Paul Scherrer Institute in Switzerland have achieved a breakthrough with the Kagome superconductor RbV3Sb5, which breaks time-reversal symmetry (TRS) at a record high temperature of 175 Kelvin (-144.67 °F). This development is significant for quantum systems, as TRS breaking at higher temperatures could lead to more practical and energy-efficient quantum technologies. The tunability of TRS breaking in RbV3Sb5, depending on the material's depth, offers potential for controlling quantum properties, paving the way for advancements in quantum device performance.

"Unveiling Altermagnetism: A Breakthrough in Magnetic Science"

Researchers at the Swiss Light Source have discovered a new type of magnetism called altermagnetism, which has never been observed before. This discovery was made in collaboration with the Czech Academy of Sciences and represents a new family of magnetic materials distinct from ferromagnets and antiferromagnets, characterized by the spontaneous arrangement of electron spins.

"Unconventional Quantum Advancements: From Junk to Gems in Qubit Breakthrough"

Researchers from the Paul Scherrer Institute PSI, ETH Zurich, and EPFL challenge the conventional belief that solid-state qubits require ultra-clean environments, as they discovered that dense arrays of qubits with long lifetimes can emerge in seemingly messy settings. Led by Gabriel Aeppli, the team densely packed rare-earth ions, specifically terbium, into yttrium lithium fluoride crystals, proposing a novel approach to quantum design that defies the minimalist principle of keeping it clean and clutter-free.
