Most networks with atom-like qubits operate at visible or near-ultraviolet wavelengths and require conversion to the telecom band for long-distance communication, which reduces efficiency and potentially introduces noise. Here we report high-fidelity entanglement between ytterbium-171 atoms and optical photons generated directly in the telecommunication band, where fibre loss is low. The nuclear spin of the atom is entangled with a single photon in the time-bin basis, yielding a high atom-measurement-corrected atom–photon Bell state fidelity. This can be further improved by addressing photon measurement errors. By imaging the atom array onto an optical fibre array, we also implement a parallelized networking protocol that can increase the remote entanglement rate proportionately with the number of channels. We also preserve coherence on a memory qubit during operations on communication qubits. These results support the integration of atomic systems into scalable quantum networks.","PeriodicalId":19100,"journal":{"name":"Nature Physics","volume":"41 1","pages":""},"PeriodicalIF":19.6,"publicationDate":"2025-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145035384","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, existing rigorous protocols applicable to general target states have potentially prohibitive resource requirements in the form of either deep quantum circuits or exponentially many single-qubit measurements. Here we prove that almost all n-qubit target states, including those with exponential circuit complexity, can be certified from only O(n2) single-qubit measurements. Given access to the target state’s amplitudes, our protocol requires only O(n3) classical computation. This result is established by a technique that relates certification to the mixing time of a random walk. Our protocol has applications for benchmarking quantum systems, for optimizing quantum circuits to generate a desired target state and for learning and verifying neural networks, tensor networks and various other representations of quantum states using only single-qubit measurements. We show that such verified representations can be used to efficiently predict highly non-local properties of a synthesized state that would otherwise require an exponential number of measurements on the state. We demonstrate these applications in numerical experiments with up to 120 qubits and observe an advantage over existing methods such as cross-entropy benchmarking.","PeriodicalId":19100,"journal":{"name":"Nature Physics","volume":"35 1","pages":""},"PeriodicalIF":19.6,"publicationDate":"2025-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145009271","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we report superconductivity in a distinct hybrid nickelate, La5Ni3O11, formed by alternating stacks of La3Ni2O7 and La2NiO4 layers. This nickelate also exhibits a density-wave transition at approximately 170 K near ambient pressure. With increasing pressure, this density-wave transition shifts to higher temperatures and abruptly disappears around 12 GPa, followed by the emergence of superconductivity, indicating a first-order phase transition. But the optimal superconductivity with large superconducting volume fraction is observed at approximately 21 GPa with ({T}_{{rm{c}}}^{{;rm{zero}}}) = 54 K. High-pressure X-ray diffraction experiments reveal a structural phase transition from an orthorhombic structure to a tetragonal structure at lower pressure. Notably, this structural change has minimal impact on the density-wave or superconducting phases, suggesting a limited role of lattice degrees of freedom in this material. These findings establish La5Ni3O11 as a new superconducting member of the Ruddlesden–Popper nickelate family and offer valuable insights into the interplay between structure, electronic order and superconductivity in hybrid nickelates.","PeriodicalId":19100,"journal":{"name":"Nature Physics","volume":"128 1","pages":""},"PeriodicalIF":19.6,"publicationDate":"2025-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144995522","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Tau, a neuronal microtubule-associated protein, is well known for its role in stabilizing microtubule tips and promoting microtubule bundling. Here we demonstrate that tau also modulates microtubule lattice dynamics. Although tau lacks enzymatic activity, it significantly accelerates tubulin exchange within the lattice, particularly at topological defect sites. Our findings indicate that tau enhances lattice anisotropy by stabilizing longitudinal tubulin–tubulin interactions while destabilizing lateral ones, thereby enhancing the mobility and annihilation of lattice defects. These results challenge the traditional view of tau as merely a passive stabilizer, revealing its active role in dynamically remodelling the microtubule lattice structure. Beyond its known role in stabilizing microtubules, it is now shown that tau protein actively promotes lattice defect repair by enhancing tubulin turnover at topological defects.","PeriodicalId":19100,"journal":{"name":"Nature Physics","volume":"21 10","pages":"1616-1628"},"PeriodicalIF":18.4,"publicationDate":"2025-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41567-025-03003-7.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144983375","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
