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…
Metallic State of Low Mobility Silicon at High Carrier density induced by an Ionic Liquid
JJ Nelson, A. M. Goldman
High mobility and dilute two-dimensional electron systems exhibit metallic behavior down to the lowest experimental temperatures. In studies of ionic liquid gated insulating silico…
