Advanced Science, EarlyView.An unambiguous quantum state discrimination for two nonorthogonal states is demonstrated using a single ion. By implementing a non‐Hermitian Hamiltonian with parity‐time‐reversal (PT) symmetry, two candidate states evolve with different speed and become orthogonal at specific time, hence can be discriminated unambiguously. Experiments are performed for

Polymorphism Crystal Structure Prediction with Adaptive Space Group Diversity Control
Advanced Science, EarlyView.Polymorphic materials exhibit diverse properties despite identical compositions, but predicting their crystal structures remains challenging. This study introduces ParetoCSP2, a multi‐objective genetic algorithm incorporating genotypic age, energy, and space group diversity.

Millikelvin Intracellular Nanothermometry with Nanodiamonds
Advanced Science, EarlyView.Nanothermometry in living cells is crucial for understanding heat diffusion and advancing cellular biology and drug discovery. Previous studies have reported controversial intracellular temperature variations. Using nanodiamond nanothermometry in macrophages, it is found that, in such experimental setting, apparent temperature changes are actually due ...

Two Types of Non‐Abelian Topological Phase Transitions Under Duality Mapping in 1D Photonic Chains
Advanced Science, EarlyView.In this work, two types of non‐Abelian phase transitions are revealed. The first type is the braided‐node type, signified by the Dirac degeneracy node moving into or out of the unit circle. The second type corresponds to the emerging of nodal‐line degeneracy which intersects with unit circles.

Advanced Science, EarlyView.With the self‐assembled monolayer (SAM), external quantum efficiencies and dissymmetry factors for circularly polarized electroluminescence are simultaneously enhanced for chiral perovskite red spin‐light emitting diodes (spin‐LEDs). These are ascribed to the improvements of magneto‐chiroptical and electronic properties.

Superconductivity in Hourglass Dirac Chain Metals (Ti, Hf)IrGe
Advanced Science, EarlyView.We report the discovery of ternary germanide superconductors MIrGe (M = Ti, Hf) that host hourglass Dirac chains protected by nonsymmorphic symmetry. These compounds exhibit bulk type‐II superconductivity with fully gapped states and preserved time‐reversal symmetry, as confirmed by µSR measurements.
