Seminar: Is Perfect Quantum State Transfer Possible? Room: 310 A deeply engrained insight in our thinking about the time evolution of a quantum mechanical wave function is the idea of "spreading of the wave packet". Our knowledge of the position, already limited initially by the uncertainty principle, subsequently becomes increasingly nebulous. In the first part of this talk, I will describe how to construct a simple tight-binding Hamiltonian for which this is not the case. The time evolution can perfectly transport an excitation from one side of a chain to another. I'll then discuss the experimental realization of this Hamiltonian in 1D, and a Monte Carlo procedure to engineer more general Hamiltonians which give efficient quantum information transfer in a superconducting quantum circuit featuring thirty-six tunable qubits where "real-world" effects constrain the system. We will see that the resulting models can yield a protocol for transferring few-particle quantum states in a two-dimensional quantum network. These include single-qubit excitations, but also two-qubit entangled states and two excitations for which many-body effects are present. Finally, I will describe our insight into these `black box' Hamiltonians which emerge from the Monte Carlo in terms of their level spacing distribution and quantum chaotic behavior.
