  • The interaction between correlated states and the excitonic emission coherence in van der Waals moiré systems remains largely unexplored. Here, the authors report evidence of enhanced interlayer exciton emission coherence in twisted WSe2/MoS2 heterobilayers, attributed to exciton-exciton and exciton-electron interactions.

  • Non-reciprocal charge transport refers to the different resistance between positive and negative current, and is fundamental in a variety of applications, for instance, current rectification. Some materials exhibit intrinsic nonreciprocal transport, but manipulation of this can be challenging. Here, the authors demonstrate large non-reciprocal transport which can be switched magnetically, is stacking dependent, and can be tuned via an applied gate voltage.

  • Silicon vacancy centres in diamond have been identified as potential highly efficient solid-state qubits for on-chip integration. Here, Zhouet al. demonstrate coherent control of silicon vacancy centres in nanodiamonds and observe Autler-Townes splitting, Mollow triplet and Rabi oscillations.

  • Owing to their valley degree of freedom, atomically thin transition metal dichalcogenides show promise for valleytronics. Here, the authors leverage the dark excitons of two-dimensional van der Waals heterostructures to demonstrate a microsecond valley polarization memory effect.

  • Monolayer transition metal dichalcogenides host a valley splitting in magnetic field analogous to the Zeeman effect. Here, the authors report that the Zeeman splitting still persists in bilayers of MoTe2 without lifting the valley degeneracy, due to spin–valley-layer coupling.

  • Moiré materials, where two van der Waals layers are stacked together with a small twist angle has proven to be a rich playground for exotic phases, with some materials, such as twisted MoTe2 being found to host quantum anomalous and fractional hall states among others. Here, An, Pan, Qiu and coauthors add to this, observing ferromagnetism in the second moiré band of twisted MoTe2.

  • Researchers propose a new type of multiphoton entangled state and demonstrate its working principles of measurement-based quantum computation in correlation space. With four- and six-qubit states, they realize a universal set of single-qubit rotations, two-qubit entangling gates and further Deutsch's algorithm.

  • Creating entangled photon states becomes technologically ever more difficult as the number of particles increases, and the current record stands at six entangled photons. However, using both their polarization and momentum degrees of freedom, up to ten-qubit states can be encoded in ‘only’ five photons, as has now been demonstrated.

  • The detection of a single photon heralds the projection of two remote spins onto a maximally entangled state. This has been demonstrated for quantum-dot hole spins, featuring a fast generation rate that could enable quantum technology applications.

  • Nonlinear responses in transport measurements can unveil specific material properties not accessible with linear measurements. In thick Td-MoTe2 samples, a third-order nonlinear Hall effect dominates over lower-order contributions and is linked to the Berry-connection polarizability tensor.
