  Quantum chaotic kicked top model is implemented experimentally in a two qubit
system comprising of a pair of spin-1/2 nuclei using Nuclear Magnetic Resonance
techniques. The essential nonlinear interaction was realized using indirect
spin-spin coupling, while the linear kicks were realized using RF pulses. After
a variable number of kicks, quantum state tomography was employed to
reconstruct the single-qubit density matrices using which we could extract
various measures such as von Neumann entropies, Husimi distributions, and
Lyapunov exponents. These measures enabled the study of correspondence with
classical phase space as well as to probe distinct features of quantum chaos,
such as symmetries and temporal periodicity in the two-qubit kicked top.
