We demonstrate a programmable thin-film lithium niobate photonic circuit capable of high-brightness generation and reconfigurable projection of path-encoded Bell states with high fidelity.

The contribution of ether lipid species in cancer cell fate has not been fully understood yet. Here the authors show that malignant cancer cells employ ether lipids to modulate membrane biophysical properties, enhancing iron endocytosis and ferroptosis susceptibility.

A semiconductor quantum dot can passively mediate interactions between two photons, enabling the creation of entangled photon states.

Qubit-cavity entanglement can be used for quantum information processing and for investigating the quantum-to-classical transition with high control. Here, the authors characterize the entanglement between an artificial atom and a cat state and its susceptibility to decoherence through Bell test witnesses.

This study develops a climate health vulnerability index for New York State, presenting an updated modeling framework and showing through sensitivity analyses that design choices affect the identification of vulnerable populations.

The triangle causal structure represents a departure from the usual Bell scenario, as it should allow to violate classical predictions without the need for external inputs setting the measurement bases. Here the authors realise this scenario using a photonic setup with three independent photon sources.

Chronic stress disrupts the brain vasculature and contributes to mood disorders, but mechanisms of resilience remain unclear. Here, the authors show that enriched environments increase astrocytic Fgf2 to prevent stress-induced vascular alterations and depressive behavior with relevance to human depression.

Improving neuraminidase content of influenza vaccines is a major focus of vaccine development. Here the authors present safety and immunogenicity of seasonal influenza mRNA vaccine candidates simultaneously encoding hemagglutinin and neuraminidase antigens in a first in-human study.

In this study, authors employ fragment-based lead discovery to identify WRN inhibitors. The fragment hits reveal an additional allosteric pocket and uncover a previously uncharacterized structural conformation of the WRN helicase domain with unique orientations of the ATPase domains

Future quantum communication technologies require entanglement between stationary and flying qubits, in systems that are inherently scalable. To this end, De Greveet al.present full state tomography of a qubit pair formed by entangling a quantum dot spin and a photon, with a fidelity of over 90%.

Quantum repeaters are a fundamental building block for long-distance quantum communication, yet they face challenges from loss and operational errors. The authors introduce a two-way repeater protocol leveraging multiplexing and application-aware distillation, demonstrating superior performance and reduced resource demands compared to one-way schemes, even in scenarios previously thought to favor the latter.

Here, the authors look at present day and medieval genome samples from Northern France to piece together demographic history and population structure across Brittany and the Loire basin.

Wastewater-based surveillance tends to focus on specific pathogens. Here, the authors mapped the wastewater virome from 62 cities worldwide to identify over 2,500 viruses, revealing city-specific virome fingerprints and showing that wastewater metagenomics enables early detection of emerging viruses.

Chronic care manages long-term, progressive conditions, while acute care handles short-term ones. Here, authors show chronic conditions account for most of the global health burden, with 68% of DALYs and 93% of YLDs attributed to chronic care needs.

Here, Brotherton and colleagues sequence 39 mitochondrial genomes from ancient human remains. They track population changes across Central Europe and find that the foundations of the European mitochondrial DNA pool were formed during the Neolithic rather than the post-glacial period.

An electrically driven on-chip light source of entangled photon pairs is developed by combining an InP gain section and Si₃N₄ microrings. A pair generation rate of 8,200 counts s⁻¹ and a coincidence-to-accidental ratio of more than 80 are achieved around the wavelength of 1,550 nm.

Arguably, the most counterintuitive aspects of quantum mechanics are indeterminacy of physical quantities and ambiguity of wave/particle behaviour prior to measurement. Terno et al.propose an experiment to test hidden-variable models that aim to restore objectivity and determinism in quantum theory.

Combining high-speed AFM, single molecule recognition force spectroscopy, and molecular dynamics simulations Zhu, Canena, Sikora et al. characterize the interaction dynamics of the trimeric spike protein of SARS-CoV-2 wt, and delta and omicron variants with its entry receptor ACE2. While delta variant increases avidity by multivalent binding to ACE2, omicron variant shows an extended binding lifetime.

Deterministic sources of entangled photons are important for photonic quantum networks, but many applications are only possible when their wavelengths are tunable. Here, the authors use on-chip strain engineering to demonstrate such a source with silicon-integrated InAs/GaAs quantum dots.

The CMS Collaboration reports the measurement of the spin, parity, and charge conjugation properties of all-charm tetraquarks, exotic fleeting particles formed in proton–proton collisions at the Large Hadron Collider.

A system based on trapped rubidium atoms for generating quantum secure keys between distant users is presented, which could operate in a device-independent fashion.

Quantum computing platforms allowing quantum error correction usually rely on complex redundant encoding within multiple two-level systems. Here, instead, the authors realize a CNOT gate between two qubits encoded in the multiphoton states of two microwave cavities nonlinearly coupled by a transmon.

Transferring quantum information is a fundamental task, but doing so with high fidelity is a challenging task. Here, the authors implement the perfect state transfer protocol to a photonic qubit, entangled with a second one in a different location, across eleven coupled waveguides.

CaBLAM is a bioluminescent genetically encoded calcium indicator that delivers high-contrast signals as shown in cell culture, in the in vivo mouse brain and in zebrafish larvae.

Heralded entanglement between two independently trapped single rubidium atoms is generated over long telecom fibre links using quantum frequency conversion in an important step towards the realization of large-scale quantum network links.

Geospatial estimates of the prevalence of anemia in women of reproductive age across 82 low-income and middle-income countries reveals considerable heterogeneity and inequality at national and subnational levels, with few countries on track to meet the WHO Global Nutrition Targets by 2030.

Uncorrected noise prevents quantum computers from running deep algorithms and outperforming classical machines. A method is now reported that allows noisy shallow quantum algorithms to be used to solve classically hard problems.

The authors report on an experimental study of attosecond time delays of photoelectrons emitted from CO₂ molecules. This clarifies the role of internal dynamics of ions and ionelectron entanglement on the photoionization dynamics.

Electron-spin resonance spectroscopy can detect radical species in live cells, but the method suffers from limitations of spin-label stability and selectivity. Here, flavoproteins are employed as genetically encoded spin probes to reveal structural features of bacterial chemotaxis proteins in cell.
