Despite exhibiting ferroelectric features, SrTiO3 fails to display long-range polar order at low temperatures due to quantum fluctuations. An ultrafast X-ray diffraction experiment now probes polar dynamics of this material at the nanometre scale.

- Shape-recovering liquidsNature Physics, Published online: 04 April 2025; doi:10.1038/s41567-025-02865-1 Placing particles at the interface between immiscible fluids usually enhances emulsification. However, now it is shown that if the particles are ferromagnetic, emulsification is suppressed and a non-planar recoverable interfacial shape develops.
- Hybrid entanglement and bit-flip error correction in a scalable quantum network nodeNature Physics, Published online: 03 April 2025; doi:10.1038/s41567-025-02831-x Nodes in a quantum network must be able to interface with photonic qubits as well as perform local quantum computations. The quantum node device presented here is capable of storing quantum information and correcting bit-flip errors.
- Coherent control of a superconducting qubit using lightNature Physics, Published online: 02 April 2025; doi:10.1038/s41567-025-02812-0 Superconducting qubits operate at microwave frequencies, but it is much more efficient to transmit information optically. Now, a superconducting qubit has been controlled with an optical signal by using a microwave–optical quantum transducer.

- Output control of dissipative nonlinear multimode amplifiers using spacetime symmetry mappingNature Physics, Published online: 01 April 2025; doi:10.1038/s41567-025-02853-5 In many optical systems with time-reversal symmetry, it is possible to control the output waves by shaping the input fields. Now a scheme is presented that works for multimode fibres that lack time-reversal symmetry due to thermal effects.
- Thermopower probes of emergent local moments in magic-angle twisted bilayer grapheneNature Physics, Published online: 31 March 2025; doi:10.1038/s41567-025-02849-1 It is well known that flat bands exist in magic-angle twisted bilayer graphene. Now thermopower measurements show that the strong correlations between electrons in these bands result in the formation of local moments.
