- Scientists discover strange “narwhal” waves that trap light beyond known limits
Physicists at Peking University have discovered a new method to confine light beyond conventional limits using dielectric materials instead of metals. The breakthrough involves narwhal-shaped wavefunctions that trap light at deep-subwavelength volumes through a singular dispersion equation. This advance, called singulonics, could enable ultra-efficient photonic chips, quantum technologies, and high-resolution imaging tools.
- Quantum coherent manipulation and readout of superconducting vortex states
Vortices trapped in superconducting granular aluminium films can behave as a quantum two-level system and be manipulated and read out, suggesting potential use in future quantum technologies. The discovery was published online in Nature on May 6, 2026. This breakthrough could lead to advancements in quantum technologies.
- Quantum systems can remember and forget at the same time, scientists discover
Quantum systems can 'remember' their past even when they appear not to, as scientists discovered that memory depends on observation perspective. The study reveals systems can seem memoryless and memory-filled simultaneously, potentially revolutionizing quantum technology design.
