Nanostructuring endows metals with exceptional mechanical and functional properties, enabled by deformation incompatibilities and dense boundaries1,2. Lightweight structural metals, exemplified by titanium (Ti) alloys, possess high specific strength, corrosion resistance and versatile phase stability, rendering them particularly attractive for nanoscale structural engineering3. However, achieving fully nanostructured bulk metals remains difficult, especially for components with complex geometries required in practical applications. The formation of nanostructures in metals demands localized non-equilibrium thermodynamic and kinetic conditions, including extreme temperature, stress or compositional fields that drive the accumulation of crystalline defects to densities characteristic of nano-architectures4,5,6. Yet these conditions are rarely attainable in existing industrial metallurgical routes, as these processes inevitably drive materials towards macroscopic thermodynamic equilibrium. Established methods such as sputtering7,8, electrodeposition9,10 and severe plastic deformation11,12,13 have delivered striking proof-of-concept demonstrations of metals with nanoscale architecture and outstanding properties. However, their applicability is restricted by geometric constraints and low productivity, leaving a persistent gap between laboratory successes and industrial implementation. Bottom-up metal additive manufacturing (AM), such as laser powder bed fusion (LPBF), offers a practical and efficient approach to address this gap. Under programmed laser scanning strategies, metal powders are selectively melted and resolidified layer by layer, fabricating components with extreme thermal gradients,...

Superconducting qubit noise protection takes a new form: a seven-member international team demonstrates theoretically that a qubit chain with alternating XX-YY ultrastrong coupling drives dephasing to exactly zero and halves relaxation, eliminating phase noise at the hardware level without quantum error correction overhead.

Deterministic single-photon sources are indispensable core devices for quantum information technology, yet high-performance implementation remains a long-standing bottleneck for linear optical quantum computing. We propose a feasible scheme for deterministic single-photon emission based on a $\trian
