Bistability, chaos and chaos-to-hyperchaos transition in a few-qubit chain. — •Alexandre Zagoskin and Alexander Balanov — Department of Physics, Loughborough University, Loughborough, UK

Based on numerical simulations, we predict that an externally driven chain of a few qubits with dissipation will demonstrate transitions between several stable regimes and chaotic behaviour due to bistability, similar to the behaviour predicted for Rydberg atoms. The system also demonstrates a transition from chaotic to hyperchaotic behaviour as the number of qubits changes from 4 to 5. We argue that the transition is determined by the dimensionality of the Hilbert pace of the system and can be observed in a system of realistic superconducting qubits.
