“…This paper focuses, for the most part, on the first of these questions, investigating the entangling power of the Schack-Caves class of quantum baker's maps. Previous investigations of entanglement in quantized chaotic systems, for the most part, have dealt with the correlations induced by coupling two or more independent systems together [13,14,15,16,17,18,19,20,21,22]. Our approach here is quite different: each of our quantum baker's maps lives in a Hilbert space with a qubit tensor-product structure; strings of qubits form a natural basis, anchoring Hilbert space to the corresponding classical phase space, and the quantum dynamics of our baker's maps is defined explicitly in terms of this connection.…”
