Purity benchmarking study of error coherence in a single Xmon qubit
Auda Zhu, Jérémy H. Béjanin, Xicheng Xu +1
In this study, we employ purity benchmarking (PB) to explore the dynamics of gate noise in a superconducting qubit system. Over 1110 hours of observations on an Xmon qubit, we simu…
The Quantum Socket and DemuXYZ-Based Gates with Superconducting Qubits
J. H. Béjanin, C. T. Earnest, M. Mariantoni
Building large-scale superconducting quantum computers requires two complimentary elements: scalable wiring techniques and multiplex architectures. In our previous work [Béjanin et…
Fluctuation Spectroscopy of Two-Level Systems in Superconducting Resonators
J. H. Béjanin, Y. Ayadi, X. Xu +3
Superconducting quantum computing is experiencing a tremendous growth. Although major milestones have already been achieved, useful quantum-computing applications are hindered by a…
Interacting Defects Generate Stochastic Fluctuations in Superconducting Qubits
J. H. Béjanin, C. T. Earnest, A. S. Sharafeldin +1
Amorphous dielectric materials have been known to host two-level systems (TLSs) for more than four decades. Recent developments on superconducting resonators and qubits enable deta…
Resonant Coupling Parameter Estimation with Superconducting Qubits
J. H. Béjanin, C. T. Earnest, Y. R. Sanders +1
Today's quantum computers are comprised of tens of qubits interacting with each other and the environment in increasingly complex networks. In order to achieve the best possible pe…
Mitigating coherent leakage of superconducting qubits in a large-scale quantum socket
T. G. McConkey, J. H. Béjanin, C. T. Earnest +4
A practical quantum computer requires quantum bit (qubit) operations with low error rates in extensible architectures. We study a packaging method that makes it possible to address…
The Quantum Socket: Three-Dimensional Wiring for Extensible Quantum Computing
J. H. Béjanin, T. G. McConkey, J. R. Rinehart +11
Quantum computing architectures are on the verge of scalability, a key requirement for the implementation of a universal quantum computer. The next stage in this quest is the reali…
