My research interests

My overall interest is how circuit-QED can be used in the construction of processors and memories for quantum computation. Within this field my research is focused on developing novel readout protocols based on non-linear effects in the Jaynes-Cummings model of a qubit coupled to a microwave resonator. In particular I study a phenomenon known as bistability in which a driven anharmonic oscillator has two different steady state modes of oscillation with different amplitudes and phases. In collaboration with experimental groups we hope to harness this effect to design new and more simple methods of high fidelity qubit readout which differ from previous applications of bistability such as the Josephson Bifurcation Amplifier.
