This talk will focus primarily on two areas of recent research. One area is the study of a circuit in which the qubit-cavity and the cavity-feedline coupling can be turned on and off, which helps to isolate the qubit. Too, by carefully choosing the detuning and interaction time, a recurrence in the qubit-cavity dynamics can be exploited in a way that makes it possible to perform very fast, high-fidelity, QND measurements. Here, the qubit measurement is performed in a step-by-step process, where the qubit and cavity interact in a time-dependent manner and the cavity state can be amplified, squeezed, and released for measurement. Second, one of the most promising applications of noisy intermediate-scale quantum computers involves simulating molecular Hamiltonians using the variational quantum eigensolver. Dr. Gard will discuss that encoding symmetries of the simulated Hamiltonian in the VQE ansatz reduces both classical and quantum resources compared to other widely available ansatze. Through simulations of a two hydrogen chain molecule, these improvements can be verified to persist in the presence of noise. This simulation is performed with IBM software using noise models from real devices and on public IBMQ hardware. Dr. Gard also will demonstrate how these techniques can be engaged to find molecular excited states of various symmetries using a noisy processor.
