    "abstract": "We analyze the consequences of iterative measurement-induced nonlinearity on\nthe dynamical behavior of qubits. We present a one-qubit scheme where the\nequation governing the time evolution is a complex-valued nonlinear map with\none complex parameter. In contrast to the usual notion of quantum chaos,\nexponential sensitivity to the initial state occurs here. We calculate\nanalytically the Lyapunov exponent based on the overlap of quantum states, and\nfind that it is positive. We present a few illustrative examples of the\nemerging dynamics.",
