A violation of Bell’s inequality would prove that a classical deterministic view of the universe is incorrect; however, despite long-standing efforts, irrefutable experimental proof of such a violation has yet to be produced. Teo et al. propose a realistic scenario that may finally overcome this challenge.

Entangled particles some distance apart can be used to show the strikingly nonlocal nature of quantum mechanics. Here the authors generate spatially separated pairs of helium atoms by colliding Bose-Einstein condensates and show that they are entangled by observing nonlocal correlations.

Researchers demonstrate that Bell's measure — a commonly used test of quantum nonlocality — can be used in classical optical schemes to separate incoherence associated with statistical fluctuations from incoherence based on correlation. This technique may be useful for quantum information applications such as classical optical coherence theory and optical signal processing.

Self-DNA has been implicated in the activation of cGAS/STING/IFN-I responses in autoimmunity and inflammatory diseases. Here the authors show that macrophage uses a process termed ‘nucleocytosis’ to extract nuclear DNA from lysosome-impaired, dying target cells, thereby activating downstream cGAS-STING signaling and IFN-I production.

A four-qubit processor of three phosphorus nuclear spins and an electron spin in silicon enables the implementation of a three-qubit Grover’s search algorithm with 95% fidelity.

The authors in this work present a study with multiplexed gene editing that is used to assess all possible mutations at a native drug binding site. The approach yields data that predicts spontaneous resistance, that aligns with in silico predictions, and that promises to facilitate drug discovery.

While several advancements have been made in the use of on-demand solid-state quantum emitters for quantum communication, using them to realise a quantum relay among remote parties had not been realised so far. Here, the authors fill this gap by realising all-photonic quantum state teleportation with photons generated by distinct remote quantum dots.

Reconfigurable arrays of up to 448 neutral atoms are used to implement and combine the key elements of a universal, fault-tolerant quantum processing architecture and experimentally explore their underlying working mechanisms.

The emergent electric field induced by pinned magnetic solitons remains poorly understood. Now the dissipative motion of magnetic domain walls under an alternating current in Weyl magnet NdAlSi devices is shown to induce a large emergent electric field.

Practical implementations of quantum communication need to securely deliver information over long distances without line-of-sight. Towards this goal, Cuevas et al.use an actively stabilized interferometer to close the geometry loophole for a Bell inequality violation over 1 km of optical fibre.

Entangled local states can be made capable of violating Bell inequalities via nonlocality activation. Typical theoretical approaches require processing many copies of the original state and performing joint measurements on the ensemble. Here, instead, the authors experimentally demonstrate how to do so using a single copy of the state, broadcasting it to two spatially separated parties within a three-node network.

The APOE-ε4 allele is the strongest genetic risk factor for late-onset Alzheimer’s disease, but it is not deterministic. Here, the authors show that common genetic variation changes how APOE-ε4 influences cognition.

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.

Fusion-based quantum computing relies on small entangled resource states that are then fused together probabilistically via linear optical circuits.
