Hybrid entanglement and bit-flip error correction in a scalable quantum network node
Nature 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 light
Nature 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 mapping
Nature 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.

Good feeders make good neighbours
Nature Physics, Published online: 31 March 2025; doi:10.1038/s41567-025-02793-0
The transition from single cells to multicellularity is a key but not well-understood step in animal evolution. A study shows that loosely-organized colonies of attached single-celled organisms can improve feeding through hydrodynamic cooperation.

Yielding behaviour of active particles in bulk and in confinement
Nature Physics, Published online: 31 March 2025; doi:10.1038/s41567-025-02843-7
Assemblies of active particles display a range of dynamical phenomena. Simulations now show that the transition of an assembly of active particles from a jammed to a fluidized state is similar to the process of mechanical yielding seen in amorphous solids.

Cooperative hydrodynamics accompany multicellular-like colonial organization in the unicellular ciliate <i>Stentor</i>
Nature Physics, Published online: 31 March 2025; doi:10.1038/s41567-025-02787-y
How unicellular organisms evolved into multicellular ones is an open question. Now, using unicellular Stentor coeruleus as a model system, the transition between isolated individuals and a coordinated colony is shown to benefit all colony members.
