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…
Material matters in superconducting qubits
Conal E. Murray
The progress witnessed within the field of quantum computing has been enabled by the identification and understanding of interactions between the state of the quantum bit (qubit) a…
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…
