Weakly Flux-Tunable Superconducting Qubit
José M. Chávez-Garcia, Firat Solgun, Jared B. Hertzberg +3
Flux-tunable qubits are a useful resource for superconducting quantum processors. They can be used to perform cPhase gates, facilitate fast reset protocols, avoid qubit-frequency c…
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…
Investigating microwave loss of SiGe using superconducting transmon qubits
Martin Sandberg, Vivekananda P. Adiga, Markus Brink +6
Silicon-Germanium (SiGe) is a material that possesses a multitude of applications ranging from transistors to eletro-optical modulators and quantum dots. The diverse properties of…
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…
Ultrahigh Vacuum Packaging and Surface Cleaning for Quantum Devices
M. Mergenthaler, S. Paredes, P. Müller +7
We describe design, implementation and performance of an ultra-high vacuum (UHV) package for superconducting qubit chips or other surface sensitive quantum devices. The UHV loading…
