Description

Research Topic Description, including Problem Statement:

We seek to understand the interaction between atoms and surfaces when the atoms are very close to the surface (100 nm – 100 um). The atoms can be neutral, charged, or molecules. This topic has been widely studied over many decades [1]. Atoms are often captured near surfaces to explore a pathway towards compact integrated systems where chip wires carrying currents combined with integrated photonics may offer a plethora of advantages in fields such as trapped ion quantum computing, ultra-cold neutral atom interferometry, and quantum clocks. However, at these very small atom surface distances, several problems arise. Of particular interest is solving some of the challenges encountered by trapped ion devices (e.g. anomalous heating) [2]. Such deleterious surface issues maybe caused by a combination of different effects. It is of great interest to the government to quantify such effects and work towards their minimization or elimination. A thorough study of this field shall benefit efforts aimed at improving qubit fidelity for quantum computing or making chip-based quantum sensors. 

Example Approaches:

The approach to solve deleterious surface effect problem is two-fold: a view from physicists and another view from material scientists. The judicious approach should be a combination of the two perspectives and to attack this problem at a fundamental level to identify why some approaches are successful and some not. It is commonly known that for trapped-ions, cryogenically cooling the chip reduces the heating rate, hence many trapped-ion scientists are heading that way. Another method to mitigate the heating problem is ion-milling in-situ or ex-situ which is understood to eject much of the contaminants that are present on the chip. This topic encourages a materials-first approach, where a detailed characterization and understanding of microscopic material properties could lead to advances in qubit performance levels.

Relevance to the Intelligence Community (IC):

High fidelity qubit control is required for fault-tolerant quantum computing. Often the accuracy of gate operations is limited by the materials, interfaces and defects that make-up the qubit and its surrounding environment. This topic aims to overcome and deepen the understanding of this limitation by uncovering strong correlations between quantum gates and state-of-the-art material characterization techniques.
