How Correlated Adsorbate Dynamics on Realistic Substrates Can Give Rise to 1/ω Electric-Field Noise in Surface Ion Traps
Benjamin Foulon, Keith G. Ray, Chang-Eun Kim +3
Ion traps are promising architectures for implementing scalable quantum computing, but they suffer from excessive "anomalous" heating that prevents their full potential from being…

Electric-field noise from thermally-activated fluctuators in a surface ion trap
Crystal Noel, Maya Berlin-Udi, Clemens Matthiesen +4
We probe electric-field noise near the metal surface of an ion trap chip in a previously unexplored high-temperature regime. We observe a non-trivial temperature dependence with th…
