Originally demonstrated in 1956 to measure the radii of stars through photon-correlation detection, it later became a cornerstone of modern quantum optics. Here we connect Hanbury Brown and Twiss interferometry to the physics of scintillation, the process of spontaneous light emission upon excitation by high-energy particles, such as X-rays. By revealing the underlying photon bunching in the scintillation process, we use the photon correlations ({g}^{left(2right)}left(tau right)) to quantify the intrinsic light emission properties of the scintillator, specifically the emission time and the number of optical photons emitted per X-ray photon. This approach provides a characterization method that we benchmark on a wide gamut of scintillators, including several rare-earth-doped (and undoped) oxide single-crystal scintillators and perovskite nanocrystals, thereby showing the dependence of their properties on temperature and X-ray flux. Our method is particularly important for nano- and microscale scintillators, whose properties are challenging to quantify by conventional means. We extract the scintillation properties even in quantum-dot superlattices of only a few hundreds of nanometres and observed strong photon bunching (({g}^{left(2right)}left(0right) > 50)). Our research paves the way for the broader use of methods from quantum optics for studying materials with complex optical properties in extreme regions of the electromagnetic spectrum.","PeriodicalId":18926,"journal":{"name":"Nature Photonics","volume":"33 1","pages":""},"PeriodicalIF":35.0,"publicationDate":"2026-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148728857","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}

Despite recent progress, high-performance isolators remain bulky off-chip components, while on-chip implementations suffer from challenging fabrication, high optical absorption or narrow optical bandwidth. Here we propose and experimentally demonstrate a magnet-free, intrinsically broadband travelling-wave isolator built from foundry-compatible components. Using radio-frequency electro-optic modulation to create synthetic motion across four parallel waveguides, we realize dynamic rotating destructive interference that continuously cancels backward-propagating light while leaving forward-propagating light unaffected. We reach ~30 dB peak isolation, maintain >24 dB isolation across a 30-nm-wavelength span with thermo-optic adjustment and show >20 dB isolation for two lasers simultaneously within 10 nm without any adjustment. The demonstration’s 770–800-nm-wavelength span covers key alkali atomic transitions, enabling on-chip laser isolation for atomic spectroscopy, laser cooling and locking applications. Our isolator approach, applicable from the visible to telecom wavelength spectrum, offers a compelling practical solution, opening the way for fully integrated atomic clocks, quantum sensors, advanced telecommunications and tunable laser systems on a single chip. Radio-frequency electro-optic modulation enables a broadband integrated optical isolator that is magnet-free.","PeriodicalId":18926,"journal":{"name":"Nature Photonics","volume":"20 9","pages":"1107-1115"},"PeriodicalIF":38.1,"publicationDate":"2026-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41566-026-01978-0.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148728854","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}

For over three decades, high-harmonic upconversion has been framed within the confines of a single-active-electron light–matter interaction featuring a well-defined cutoff photon energy. Here we demonstrate experimentally that correlated electrons can propel high-harmonic emission beyond this single-active-electron limit, markedly increasing the generated photon energies. We observe a weak secondary plateau that extends the conventional cutoff beyond 120 eV up to the water window at 280 eV. This phenomenon arises from double-electron recombination of strongly correlated electron pairs, resulting in a new cutoff scaling of up to 5.5 times the ponderomotive energy of the rescattering electrons, which notably deviates from the conventional scaling factor of 3.2. These findings reshape our fundamental understanding of the high-harmonic upconversion process and position high-harmonic generation as a potent photonic probe of attosecond-to-femtosecond electron correlations in quantum systems, opening new pathways for advanced ultrafast spectroscopy, novel attosecond source development and the exploration of strongly correlated quantum materials.

Calcium imaging has transformed neuroscience but provides an indirect and relatively slow readout of electrical activity. By directly measuring membrane potential changes, voltage imaging enables millisecond-scale recording of action potentials, subthreshold dynamics and signal propagation across neural circuits. Recent advances in voltage-sensitive dyes and genetically encoded voltage indicators have made voltage imaging increasingly practical, motivating the development of fluorescence microscopy methods optimized for high-speed acquisition. However, voltage imaging remains constrained by trade-offs among imaging speed, spatial resolution, signal-to-noise ratios and photodamage. In this Review we discuss high-speed optical microscopy strategies that address these challenges and highlight the need for co-design among voltage indicators, imaging systems and computational analysis. The Review discusses recent advances in neural voltage imaging, with an emphasis on relevant microscopy techniques and outstanding challenges in the field.","PeriodicalId":18926,"journal":{"name":"Nature Photonics","volume":"20 9","pages":"993-1005"},"PeriodicalIF":38.1,"publicationDate":"2026-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148872192","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}

Laser–plasma amplifiers show promise to realize these intensities by augmenting the final amplifier and compressor in traditional chirped-pulse-amplification architectures with a plasma-based amplification and compression stage that operates at a much higher damage threshold. Here we demonstrate amplification of an ultrabroadband (>60 nm) pulse in a laser–plasma Raman amplifier. We directly amplified seed intensities up to 3.7 × 1015 W cm−2 and measured efficiencies up to 8.7%. Single-shot SPIDER measurements show a factor-of-2 reduction in the amplified pulse duration with final powers up to 0.3 TW, a 10× improvement over previous results. Final pulse durations of 64 fs are measured. Energy transfers greater than 220 mJ from the picosecond pump into the seed result in a 30× energy amplification of a 7.6 mJ seed. These results set the stage for a compact plasma afterburner based on Raman amplification that could extend the scientific capability of existing petawatt-class laser facilities to enable experiments at the intensity frontier.

For quantum photonic systems, integrating such nonlinearities with scalable linear circuitry has been a main bottleneck, leaving most optical experiments without nonlinear operations and, consequently, incapable of achieving universality. Here we report on an extensible photonic computer that supports a universal physical gate set by seamlessly combining fully programmable, scalable linear-optical networks with integrated nonlinear modules. This platform enables a broad range of quantum computing and simulation tasks. We demonstrate the quasi-deterministic generation of optical Gottesman–Kitaev–Preskill states, which are essential resources for bosonic error correction yet had previously been realized only probabilistically. Furthermore, we simulate complex many-body quantum dynamics, exemplified by the Bose–Hubbard model. Such quantum simulation tasks have long been considered beyond the reach of photonic hardware limited to linear operations. These capabilities, enabled by our extensible architecture, establish a viable route towards photonic quantum simulation and fault-tolerant quantum computing. An extensible photonic quantum computing architecture based on a fully programmable, scalable linear-optical network has been realized, and is enhanced by two addressable modules: an inline squeezing module for injecting nonlinear resources as input states and a Kerr interaction module for implementing effective nonlinear operations.","PeriodicalId":18926,"journal":{"name":"Nature Photonics","volume":"20 10","pages":"1166-1173"},"PeriodicalIF":38.1,"publicationDate":"2026-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41566-026-01962-8.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148693527","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}
