Fig. 2: Hyperchaos in a ring of five qubits.
From: Emergence and control of complex behaviors in driven systems of interacting qubits with dissipation
a Map showing areas of (Δ, Ω) space corresponding to different regimes of long-term behavior for a ring of five qubits. Black denotes areas of hyperchaos with two positive Lyapunov exponents, green is a region of chaos with one positive Lyapunov exponent, cyan is a periodic regime, red areas correspond to quasiperiodic behavior, and white is a steady-state regime. b Variation of the four largest Lyapunov exponents with Δ; blue dots correspond to Δ increasing from 1 to 9, red dots to Δ decreasing down to 1. c A zoom of the region of b within the black rectangle. d Single-parametric bifurcation diagram corresponding to c, in which the vertical positions of each point correspond to the local maxima of w1(t). For all figures Ω = 2.5.
