    Earlier research has shown that controlling activity in the active matter can lead to either a phase change or a laminar-turbulent transition in active fluids. Authors demonstrate that it is possible to control both the phase transitions between solid, liquid, and gas states and the laminar-to-turbulent transitions in fluid phases by adjusting the activity of a phoretic medium.

    Usual multiqubit entangled states can be described using the graph formalism, where each edge connects only two qubits. Here, instead, the authors use a reprogrammable silicon photonics chip to showcase preparation, verification and processing of arbitrary four-qubit hypergraph states, where hyperedges describe entanglement within a subset of many qubits.

    Manipulating quantum information encoded in a bosonic mode requires sizeable and controllable nonlinearities, but superconducting devices’ strong nonlinearities are normally static. Here, the authors use a SNAIL to suppress static nonlinearities and use drive-dependent ones to reach universal control of a bosonic mode.
