A team of scientists proposes that modulated quantum metasurfaces can control all properties of photonic qubits, a breakthrough that could impact the fields of quantum information, communications, sensing and imaging, as well as energy and momentum harvesting.

Physicists have observed signs of a rare type of superconductivity in a material called 'magic-angle' twisted trilayer graphene. They report that the material exhibits superconductivity at surprisingly high magnetic fields of up to 10 Tesla, which is three times higher than what the material is predicted to endure if it were a conventional superconductor.

Scientists have created an ultrathin magnet that operates at room temperature. The ultrathin magnet could lead to new applications in computing and electronics -- such as high-density, compact spintronic memory devices -- and new tools for the study of quantum physics.

Using time- and spin-resolved methods at BESSY II, the physicists explored how, after optical excitation, the complex interplay in the behavior of excited electrons in the bulk and on the surface results in unusual spin dynamics. The work is an important step on the way to spintronic devices based on topological materials for ultrafast information processing.

Scientist demonstrated a new way of observing atoms as they move in a tiny quantum electronic switch as it operates. Along the way, they discovered a new material state that could pave the way for faster, more energy-efficient computing.
