Charge-noise spectroscopy of Si/SiGe quantum dots via dynamically-decoupled exchange oscillations
Elliot J. Connors, JJ Nelson, Lisa F. Edge +1
Electron spins in silicon quantum dots are promising qubits due to their long coherence times, scalable fabrication, and potential for all-electrical control. However, charge noise…
Rapid high-fidelity spin state readout in Si/SiGe quantum dots via radio-frequency reflectometry
Elliot J. Connors, JJ Nelson, John M. Nichol
Silicon spin qubits show great promise as a scalable qubit platform for fault-tolerant quantum computing. However, fast high-fidelity readout of charge and spin states, which is re…
Low-frequency charge noise in Si/SiGe quantum dots
Elliot J. Connors, JJ Nelson, Haifeng Qiao +2
Electron spins in silicon have long coherence times and are a promising qubit platform. However, electric field noise in semiconductors poses a challenge for most single- and multi…
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…
Infinite-randomness fixed point of the quantum superconductor-metal transitions in amorphous thin films
Nicholas A. Lewellyn, Ilana M. Percher, JJ Nelson +5
The magnetic-field-tuned quantum superconductor-insulator transitions of disordered amorphous indium oxide films are a paradigm in the study of quantum phase transitions, and exhib…
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…
