The Future of Quantum Computing with Superconducting Qubits
Sergey Bravyi, Oliver Dial, Jay M. Gambetta +2
For the first time in history, we are seeing a branching point in computing paradigms with the emergence of quantum processing units (QPUs). Extracting the full potential of comput…
Spectator Errors in Tunable Coupling Architectures
D. M. Zajac, J. Stehlik, D. L. Underwood +9
The addition of tunable couplers to superconducting quantum architectures offers significant advantages for scaling compared to fixed coupling approaches. In principle, tunable cou…
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…
Suppressed crosstalk between two-junction superconducting qubits with mode-selective exchange coupling
A. D. K. Finck, S. Carnevale, D. Klaus +8
Fixed-frequency qubits can suffer from always-on interactions that inhibit independent control. Here, we address this issue by experimentally demonstrating a superconducting archit…
Tunable Coupling Architecture for Fixed-frequency Transmons
J. Stehlik, D. M. Zajac, D. L. Underwood +9
Implementation of high-fidelity two-qubit operations is a key ingredient for scalable quantum error correction. In superconducting qubit architectures tunable buses have been explo…
High-fidelity superconducting quantum processors via laser-annealing of transmon qubits
Eric J. Zhang, Srikanth Srinivasan, Neereja Sundaresan +19
Scaling the number of qubits while maintaining high-fidelity quantum gates remains a key challenge for quantum computing. Presently, superconducting quantum processors with >50-qub…
