Interfacing quantum information between discrete and continuous would allow exploiting the best of both worlds, but it has been shown only for single-rail encoding. Here, the authors extend this to the more practical dual-rail encoding, realizing teleportation between a polarization qubit and a CV qubit.

Here, the authors violate a chained n-locality inequality in a network with five nodes and four independent sources, relying only on single-qubit measurements.

Myosin transduces chemical energy into mechanical work, but the mechanism remains unclear. In this work, the authors show that force-generation precedes product release and that a mutation in the active site alters the load dependence of product release.

The deep ocean is increasingly subjected to human-induced environmental change, but little is known about species-specific responses to stressors, including those from deep sea mining. This study shows that elevated temperatures and simulated sediment plumes cause physiological stress in a cosmopolitan deep-sea jellyfish, confirming the detrimental impact of seabed mining.

Entanglement between photons is easily destroyed by losses in optical systems as light propagates through it. For entanglement of orbital angular momentum, McLaren et al.show that losses caused by obstructions in the beam path can be overcome if measurements are made in the Bessel basis.

Tests of the Bell-Kochen-Specker theorem aim at showing that the measurement statistics of a single qutrit are incompatible with noncontextual realism. Here, the authors use a superconducting qutrit with deterministic readouts to violate a noncontextuality inequality, ruling out several loopholes.

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.

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.

A Bell-like experiment that discriminates between real-number and complex-number multipartite quantum systems could disprove real quantum theory.

DNA methylation is a critical component for repression of fetal haemoglobin in adult blood cells. Removing DNA methylation from the fetal haemoglobin promoter effectively upregulates the gene, opening avenues for the treatment of blood disorders.

Quantum communications operate with shared multipartite entangled states, and this has to be certified in a setting where not all parties are trusted in the same way. Here the authors propose a method to certify multipartite entanglement in asymmetric scenarios and demonstrate it in an optical experiment.
