Quantum Lunch

Anomalous heating in ion traps: what is it and can it be mitigated?

H. R. Sadeghpour
ITAMP, Harvard-Smithsonian Center for Astrophysics

Electric field noise is a hindrance to the assembly of large scale quantum computers based on entangled trapped ions. Apart from ubiquitous technical noise, experimental studies of trapped ion heating have revealed additional limiting contributions to this noise, originating from atomic processes on the electrode surfaces. In this talk, I will describe a microscopic model for this excess electric field noise, which points a way towards a systematic understanding of surface adsorbates as progenitors of electric field jitter noise.
