Monte Carlo Spin Simulations of Magnetic Noise -- The Search for Pivoting
D. L. Mickelsen, Ruqian Wu, Clare C. Yu
Superconducting quantum interference devices (SQUIDs) show great promise as quantum bits (qubits) but continue to be hindered by flux noise. The flux noise power spectra of SQUIDs…

Interacting Two-Level Systems as a Source of 1/f Charge Noise in Quantum Dot Qubits
D. L. Mickelsen, Herve M. Carruzzo, Clare C. Yu
Charge noise in semiconducting quantum dots has been observed to have a 1/f spectrum. We propose a model in which a pair of quantum dots are coupled to a 2D bath of fluctuating two…

Effects of Temperature Fluctuations on Charge Noise in Quantum Dot Qubits
Dan Mickelsen, Herve M. Carruzzo, Susan N. Coppersmith +1
Silicon quantum dot qubits show great promise but suffer from charge noise with a 1/f^αspectrum, where f is frequency and α\lesssim 1. It has recently been proposed that 1/f^αnoise…
