Anomalous Charge Noise in Superconducting Qubits
B. G. Christensen, C. D. Wilen, A. Opremcak +9
We have used Ramsey tomography to characterize charge noise in a weakly charge-sensitive superconducting qubit. We find a charge noise that scales with frequency as over 5…

Digital coherent control of a superconducting qubit
Edward Leonard, Matthew A. Beck, JJ Nelson +15
High-fidelity gate operations are essential to the realization of a fault-tolerant quantum computer. In addition, the physical resources required to implement gates must scale effi…
