Investigating the Effects of Electric Field Noise from Metallic Surfaces on Ultra-Low Temperature Ion Traps at Low Frequencies
The objective of this work is to study electric field noise from metallic surfaces at low frequencies observed in ultra-low temperature ion traps. This source of noise has been a major issue for ion trapping experiments because it heats up the cold ions several orders of magnitude faster than what was expected. This heating is a serious problem and hinders progress in the use of ions, as dependably controllable qubits, toward a scalable quantum computer. The expected benefits from this research is the determination of the frequency scaling of this anomalous heating, which will shed light on the origin of this noise and, in turn, on ways to mitigate it.
