Copper-based and iron-based compounds exhibit an interplay between magnetism and superconductivity. Now, this idea is extended to two-dimensional oxide heterostructures, where a spatially varying superconducting order is demonstrated at the EuO/KTaO₃ interface.

Cooling efficiency in thermoelectric devices decreases considerably at lower temperatures. Now thermoelectric cooling at cryogenic temperatures is directly imaged in a van der Waals semimetal.

The concept of temporal mode-locking has been leveraged to study the interplay between laser mode-locking and photonic lattices that exhibit non-Hermitian topological phenomena. The results suggest new opportunities to study nonlinear and non-Hermitian topological physics as well as potential applications to sensing, optical computing and frequency-comb design.

Excitation of magnons — quanta of spin-waves — in an antiferromagnet can be used for high-speed data processing. The addition and subtraction of two such modes opens up possibilities for magnon-based information transfer in the terahertz spectral region.

The Hamiltonian describing a quantum many-body system can be learned using measurements in thermal equilibrium. Now, a learning algorithm applicable to many natural systems has been found that requires exponentially fewer measurements than existing methods.

Despite being essential to many applications in quantum science, entanglement can be easily disrupted by decoherence. A protocol based on repetitive quantum error correction now demonstrates enhanced coherence times of entangled logical qubits.

Complexity of learning Hamiltonians from Gibbs states is an important issue for both many-body physics and machine learning. The optimal sample and time complexities of quantum Hamiltonian learning for high temperature has now been proven.

Quantum computers promise to efficiently predict the structure and behaviour of molecules. This Perspective explores how this could overcome existing challenges in computational drug discovery.

Photon-mediated entanglement in atomic ensembles coupled to cavities enables the engineering of quantum states with a graph-like entanglement structure. This offers potential advantages in quantum computation and metrology.

Combining multiparticle levitation with cavity control enables cavity-mediated interaction between levitated nanoparticles, whose strength can be tailored via optical detuning and position of the two particles.

Spin polarons, bound states of a doped carrier and a spin flip excitation, are observed in a transition metal moiré bilayer.

Mode locking, which is a common technique to produce short laser pulses, is demonstrated in a topological laser.

Most applications of surface plasmons are based on their near-field properties. These properties are now shown to be governed by nonclassical scattering between multiparticle plasmonic subsystems.

Cluster states made from multiple photons with a special entanglement structure are a useful resource for quantum technologies. Two-dimensional cluster states of microwave photons have now been deterministically generated using a superconducting circuit.

Electric dipoles are common in insulators, but extremely rare in metals. This situation may be about to change, thanks to flexoelectricity.

Although dissipation is often detrimental to the observation of topological effects, a photonic molecule driven at several incommensurate frequencies is shown to be a candidate system for quantized topological transport in synthetic dimensions.

AI needs to develop more solid assumptions, falsifiable hypotheses, and rigorous experimentation.

Attosecond interferometry measurements of photoionization delays in planar carbon-based molecules can provide information on the dimension and shape of the two-dimensional hole generated in the process.

A transducer that generates microwave–optical photon pairs is demonstrated. This could provide an interface between optical communication networks and superconducting quantum devices that operate at microwave frequencies.

Topologically protected hinge modes could be important for developing quantum devices, but electronic transport through those states has not been demonstrated. Now quantum transport has been shown in gapless topological hinge states.
