Quasiparticle tunneling as a probe of Josephson junction barrier and capacitor material in superconducting qubits
C. Kurter, C. E. Murray, R. T. Gordon +15
Non-equilibrium quasiparticles are possible sources for decoherence in superconducting qubits because they can lead to energy decay or dephasing upon tunneling across Josephson jun…
Environmental Radiation Impact on Lifetimes and Quasiparticle Tunneling Rates of Fixed-Frequency Transmon Qubits
R. T. Gordon, C. E. Murray, C. Kurter +12
Quantum computing relies on the operation of qubits in an environment as free of noise as possible. This work reports on measuring the impact of environmental radiation on lifetime…
Effects of surface treatments on flux tunable transmon qubits
M. Mergenthaler, C. Müller, M. Ganzhorn +9
One of the main limitations in state-of-the art solid-state quantum processors are qubit decoherence and relaxation due to noise in their local environment. For the field to advanc…
Merged-Element Transmons: Design and Qubit Performance
H. J. Mamin, E. Huang, S. Carnevale +12
We have demonstrated a novel type of superconducting transmon qubit in which a Josephson junction has been engineered to act as its own parallel shunt capacitor. This merged-elemen…
