Quantum errors induced by environmental noise are unavoidable and preclude the direct implementation of practical quantum computation. Fault-tolerant quantum computation offers one of the viable paths, necessitating the encoding and processing of information within logical qubits to curb such errors. Although substantial progress has been achieved recently in building silicon quantum computers, logical operations still haven’t been realized in silicon. Here we demonstrate a logical quantum processor using a phosphorus donor cluster in silicon. By implementing the [[4, 2, 2]] code, we realize the essential components for logical operations, which include fault-tolerant preparation of logical states and the characterization of a universal gate set comprising logical single-qubit and two-qubit gates. In particular, the logical T gate is achieved using the gate-by-measurement method, and magic states based on this gate are prepared. Furthermore, we execute the variational quantum eigensolver algorithm using two logical qubits and simulate the ground state of the electronic structure of the water molecule H2O. This work represents a key step towards scalable, fault-tolerant quantum computation in silicon spin qubits.
环境噪声引起的量子误差是不可避免的,它阻碍了实际量子计算的直接实现。容错量子计算提供了一条可行的途径,需要在逻辑量子比特内对信息进行编码和处理,以抑制此类错误。尽管最近在构建硅量子计算机方面取得了实质性进展,但逻辑运算仍然没有在硅上实现。在这里,我们展示了一个逻辑量子处理器,使用硅中的磷供体簇。通过实现[[4,2,2]]代码,我们实现了逻辑运算的基本组件,包括逻辑状态的容错准备和由逻辑单量子比特和双量子比特门组成的通用门集的表征。特别地,利用测量门的方法实现了逻辑T门,并基于此门制备了魔态。此外,我们使用两个逻辑量子比特执行变分量子特征求解算法,并模拟水分子H2O的电子结构的基态。这项工作代表了在硅自旋量子比特中实现可扩展、容错量子计算的关键一步。

Magnetic circular dichroism utilizing electrons or X-rays serves as a powerful tool for the investigation of magnetism in ferromagnets, but antiferromagnets pose a severe challenge to the technique due to their vanishing net magnetization. Although transmission electron microscopy has demonstrated the atomic-scale characterization of antiferromagnetism using elastically scattered electrons, separating the weak magnetic signal from the dominant electrostatic background remains challenging, and applicability is largely limited to perfect crystals. Here we develop atomic-column-resolved electron magnetic circular dichroism to resolve antiferromagnetic order using a scanning transmission electron microscope. By exploiting chirality around individual magnetic atomic columns, we localize the magnetic circular dichroism signals around the transmitted electron beam with enhanced strength and signal-to-noise ratio, enabling atomic-column magnetic measurements. Applying this technique to antiferromagnets, we not only distinguish the characteristic G-type and C-type antiferromagnetic orderings in DyFeO3 and α-Fe2O3 but also identify a one-unit-cell-thick magnetic dead layer at the buried DyScO3–SmFeO3 interface. Our work establishes a readily accessible method for atomic-scale magnetic order mapping, with potential applications in fields such as interfacial magnetism, topological magnetism, antiferromagnetism and altermagnetism.
利用电子或x射线的磁圆二色性是研究铁磁体磁性的有力工具,但由于反铁磁体的净磁化消失,对该技术构成了严峻的挑战。尽管透射电子显微镜已经证明了使用弹性散射电子的反铁磁性的原子尺度表征,但从主要静电背景中分离弱磁信号仍然具有挑战性,并且适用性很大程度上限于完美晶体。在这里,我们发展了原子柱分辨的电子磁性圆二色性,用扫描透射电子显微镜来分辨反铁磁有序。通过利用单个磁原子柱周围的手性,我们以增强的强度和信噪比定位了传输电子束周围的磁圆二色性信号,从而实现了原子柱磁测量。将该技术应用于反铁磁体中,我们不仅区分了DyFeO3和α-Fe2O3的g型和c型反铁磁有序特征,而且在埋藏的DyScO3-SmFeO3界面处发现了一个1单元格厚的磁死层。我们的工作建立了一种易于获得的原子尺度磁序映射方法,在界面磁性、拓扑磁性、反铁磁性和互变磁性等领域具有潜在的应用前景。

Hybrid perovskite–nanograting photonic architecture enables supersolidity at room temperature 混合钙钛矿-纳米光栅光子结构在室温下实现超固体

The supersolid phase is a self-organized state of matter that simultaneously exhibits the crystalline order of a solid and the frictionless flow of a superfluid. Its formation requires the simultaneous breaking of phase and translational symmetries—a stringent condition that makes experimental observation challenging. Here we show that it is possible to achieve a room-temperature supersolid phase by integrating single-crystal halide perovskites with an exciton–polariton nanograting. This architecture supports a hybrid polaritonic bound-state-in-continuum state with a large bandgap (18.2 meV) and two side modes. As the pumping intensity increases, optical parametric oscillation drives the system from a bound-state-in-continuum polariton condensate into the two side modes, forming a self-organized supersolid phase characterized by a striped one-dimensional lattice spanning the condensate. Crucially, single-shot real-space imaging shows stochastic phase selection of the stripe pattern, evidenced by strong suppression of the density modulation on multishot averaging. The observation of supersolidity is further supported by long-range spatiotemporal coherence measured interferometrically and by a non-rigid supersolid lattice. The realization of supersolidity at room temperature in a polaritonic nanograting platform can be useful to control exotic quantum orders and for exploring spontaneous symmetry breaking, quantum coherence and collective excitations in driven quantum materials.
超固相是物质的一种自组织状态,同时表现出固体的结晶秩序和超流体的无摩擦流动。它的形成需要同时打破相和平移对称——这是一个严格的条件,使实验观察具有挑战性。在这里,我们证明了通过将单晶卤化物钙钛矿与激子-极化子纳米光栅集成来实现室温超固相是可能的。该结构支持具有大带隙(18.2 meV)和双侧模式的混合极化结合态-连续态。随着泵浦强度的增加,光学参量振荡驱动系统从连续统束缚态的极化子凝聚体进入两个侧模,形成一个自组织的超固相,其特征是跨越凝聚体的一维条纹晶格。重要的是,单镜头实空间成像显示了条纹模式的随机相位选择,证明了多镜头平均对密度调制的强抑制。超固体的观测进一步得到了远程时空相干干涉测量和非刚性超固体晶格的支持。在极化纳米光栅平台上实现室温下的超固体,可以用于控制奇异量子秩序,以及探索驱动量子材料中的自发对称性破缺、量子相干性和集体激发。

Success in systemic immunotherapy against metastatic cancer hinges on the ability to achieve tumour-specific immune activation over normal tissues. Single-gate stimuli-responsive systems are not adequate at differentiating tumour versus normal tissue signals. Here we report an AND-gated nanoparticle that requires acidic pH and hypoxia signals to activate the stimulator of interferon genes (STING) pathway in systemic therapy of metastatic cancers. The dual stimuli-responsive nanoparticle consists of a small-molecule STING agonist conjugated to a pH-sensitive polymer through a hypoxia-sensitive linker. Biochemical analyses confirmed the (pH-hypoxia) AND logic truth table in STING activation. The nanoparticle agonist significantly reduced metastatic burdens in multiple immune-cold tumour models while exhibiting minimal systemic toxicity. Mechanistic investigation revealed that STING activation in tumour-resident type I dendritic cells drives CD8+ T cell priming and infiltration, which synergizes with immune checkpoint inhibitors. This AND logic nanoplatform offers a safe and efficacious therapeutic for STING-mediated immunotherapy against metastatic cancers.

对转移性癌症的全身免疫治疗的成功取决于在正常组织上实现肿瘤特异性免疫激活的能力。单门刺激反应系统不足以区分肿瘤与正常组织信号。在这里,我们报道了一种and门控纳米粒子,它需要酸性pH和缺氧信号来激活干扰素基因刺激因子(STING)通路,用于转移性癌症的全身治疗。双刺激响应纳米颗粒由小分子STING激动剂通过低氧敏感连接剂偶联到ph敏感聚合物组成。生化分析证实了STING激活的(ph -缺氧)和逻辑真值表。纳米颗粒激动剂在多种免疫冷肿瘤模型中显著减少转移负担,同时表现出最小的全身毒性。机制研究表明,肿瘤驻留型I型树突状细胞中的STING激活驱动CD8+ T细胞的启动和浸润,并与免疫检查点抑制剂协同作用。这个AND logic纳米平台为sting介导的免疫治疗转移性癌症提供了一种安全有效的治疗方法。

Computation in biological neural circuits arises from the interplay of nonlinear temporal responses and spatially distributed dynamic network interactions. Replicating this richness in hardware has remained challenging, as most neuromorphic devices emulate only isolated neuron- or synapse-like functions. Here we introduce an integrated neuromorphic computing platform in which both nonlinear spatiotemporal processing and programmable memory are realized within a single perovskite nickelate material system. By engineering symmetric and asymmetric hydrogenated NdNiO3 junction devices on the same wafer, we combine ultrafast, proton-mediated transient dynamics with stable multilevel resistance states. Networks of symmetric NdNiO3 junctions exhibit emergent spatial interactions mediated by proton redistribution, while each node simultaneously provides short-term temporal memory, enabling nanosecond-scale operation with an energy cost of ~0.2 nJ per input. When interfaced with asymmetric output units serving as reconfigurable long-term weights, these networks allow both feature transformation and linear classification in the same material system. Leveraging these emergent interactions, the platform enables real-time pattern recognition and achieves high accuracy in spoken digit classification and early seizure detection, outperforming temporal-only or uncoupled architectures. These results position protonic nickelates as a compact, energy-efficient, CMOS-compatible platform that integrates processing and memory for scalable intelligent hardware.

生物神经回路的计算来源于非线性时间响应和空间分布的动态网络相互作用的相互作用。在硬件中复制这种丰富的功能仍然具有挑战性,因为大多数神经形态设备只能模拟孤立的神经元或类似突触的功能。本文介绍了一种集成的神经形态计算平台,该平台在单一钙钛矿镍酸盐材料系统中实现了非线性时空处理和可编程存储。通过在同一晶圆上设计对称和非对称氢化NdNiO3结器件,我们将超快、质子介导的瞬态动力学与稳定的多能级电阻态结合起来。对称NdNiO3连接网络表现出由质子再分配介导的紧急空间相互作用,而每个节点同时提供短期时间记忆,实现纳秒级的操作,每次输入的能量成本约为0.2 nJ。当与作为可重构长期权重的非对称输出单元相连接时,这些网络允许在同一材料系统中进行特征转换和线性分类。利用这些紧急交互,该平台能够实现实时模式识别,并在语音数字分类和早期癫痫检测方面实现高精度,优于仅时间或非耦合架构。这些结果将质子镍酸盐定位为一种紧凑,节能,cmos兼容的平台,集成了可扩展智能硬件的处理和内存。

Evidences of subnanometre orbital diffusion length in heavy metals using terahertz emission spectroscopy 用太赫兹发射光谱研究重金属亚纳米轨道扩散长度

The orbital angular momentum of electrons offers a promising, yet underexplored, degree of freedom for ultrafast, energy-efficient information processing. As the foundation of orbitronics, understanding how orbital polarizations propagate and convert into charge currents is essential but remains elusive due to the challenge in disentangling orbital and spin dynamics in thin films. While some theoretical studies predict that orbital transport is constrained to sub-atomic-layer scales in materials, recent experiments have reported exceptionally long orbital diffusion lengths. To address this contradiction, we combine terahertz emission spectroscopy with a wedge-sample platform to systematically investigate spin and orbital transport in heavy metals with subnanometre resolution. Our measurements access the previously unexplored thin-film regimes (<3 nm), uncovering anomalous behaviours that challenge the prevailing interpretations of long-range orbital transport. We consistently find the orbital diffusion lengths (λL) to be substantially shorter than the spin diffusion lengths (λS) in heavy metals, with λL in W approaching 0.36 nm. Interface-sensitive control experiments further rule out interfacial orbital-to-charge conversion as the dominant mechanism, supporting the bulk inverse orbital Hall effect as the primary conversion process.
电子的轨道角动量为超快速、节能的信息处理提供了一个有希望的、但尚未充分开发的自由度。作为轨道电子学的基础,了解轨道极化如何传播并转化为电荷电流是必不可少的,但由于在薄膜中解开轨道和自旋动力学的挑战,仍然难以捉摸。虽然一些理论研究预测,在材料中,轨道输运仅限于亚原子层尺度,但最近的实验报道了异常长的轨道扩散长度。为了解决这一矛盾,我们将太赫兹发射光谱与楔样平台相结合,以亚纳米分辨率系统地研究了重金属中的自旋和轨道输运。我们的测量进入了以前未探索的薄膜区(< 3nm),发现了挑战远程轨道输运的主流解释的异常行为。我们一致发现重金属中的轨道扩散长度(λL)明显短于自旋扩散长度(λS),其中W中的λL接近0.36 nm。界面敏感控制实验进一步排除了界面轨道-电荷转换为主导机制的可能性,支持本体反轨道霍尔效应为主要转换过程。

As the foundation of orbitronics, understanding how orbital polarizations propagate and convert into charge currents is essential but remains elusive due to the challenge in disentangling orbital and spin dynamics in thin films. While some theoretical studies predict that orbital transport is constrained to sub-atomic-layer scales in materials, recent experiments have reported exceptionally long orbital diffusion lengths. To address this contradiction, we combine terahertz emission spectroscopy with a wedge-sample platform to systematically investigate spin and orbital transport in heavy metals with subnanometre resolution. Our measurements access the previously unexplored thin-film regimes (<3 nm), uncovering anomalous behaviours that challenge the prevailing interpretations of long-range orbital transport. We consistently find the orbital diffusion lengths (λL) to be substantially shorter than the spin diffusion lengths (λS) in heavy metals, with λL in W approaching 0.36 nm. Interface-sensitive control experiments further rule out interfacial orbital-to-charge conversion as the dominant mechanism, supporting the bulk inverse orbital Hall effect as the primary conversion process.","PeriodicalId":18915,"journal":{"name":"Nature nanotechnology","volume":"17 1","pages":""},"PeriodicalIF":38.3,"publicationDate":"2026-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147351053","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The application of messenger RNA (mRNA) beyond infectious diseases is challenged by inefficient protein production. Whereas the engineering of secondary mRNA structures has been shown to increase mRNA half-life, it remains unclear whether tertiary mRNA structures influence therapeutic efficacy. Here we develop a metal-ion-assisted RNA folding (MARF) strategy and show that, when delivered with lipid nanoparticles (LNPs), specific metals promote mRNA folding architectures that result in the amplification of protein expression by up to 7.3-fold compared with control mRNA. This effect is due to altered mechanical interactions between the mRNA LNPs and the surrounding biosystem, resulting in enhanced intracellular processing and prolonged retention of delivered mRNA in targeted cells. Administered intravenously, MARF LNPs achieved effective and durable genome editing of the clinically relevant Pcsk9 gene through treatment with a single dose. Overall, this work provides a new MARF technology for more effective mRNA therapy and highlights the potential of mechanical cues in designing nanoparticles for improved mRNA delivery.
信使RNA (mRNA)在感染性疾病之外的应用受到蛋白质生产效率低下的挑战。虽然二级mRNA结构的工程化已被证明可以增加mRNA的半衰期,但三级mRNA结构是否影响治疗效果仍不清楚。在这里,我们开发了一种金属离子辅助RNA折叠(MARF)策略,并表明,当与脂质纳米颗粒(LNPs)一起递送时,特定金属促进mRNA折叠结构,导致蛋白质表达比对照mRNA扩增高达7.3倍。这种效应是由于mRNA LNPs与周围生物系统之间的机械相互作用发生了改变,导致细胞内加工增强,mRNA在靶细胞中滞留时间延长。通过静脉注射,MARF LNPs通过单剂量治疗实现了对临床相关Pcsk9基因的有效和持久的基因组编辑。总的来说,这项工作为更有效的mRNA治疗提供了一种新的MARF技术,并强调了机械线索在设计纳米颗粒以改善mRNA递送方面的潜力。
