Experimental Study of Josephson Qubits and Oscillators
Abstract
This report results from a contract tasking University of Erlangen-Nuremberg as follows: The Grantee will investigate physical properties and improve the performance of two groups of Josephson devices: Josephson junction array oscillators and Josephson Qubits. They will continue study of series-parallel Josephson junction array oscillators from earlier research. The goal is to significantly increase the detected radiated power from 80 GHz to 120 GHz by improving the resonance frequency match between the devices and the receiver. They will also test the compact arrays of similar oscillator devices which incorporate antenna wires. Second, they will design and fabricate Josephson qubit devices for characterization from 4.2 K down to 20 mK. The energy profile will be characterized in the classical regime and projected into the quantum range and the coupling of the qubits to the environment will be examined according to the approach detailed in the technical proposal.
