Summary
- What is new: Developed a new method called exchange cooling for quantum processors that eliminates the need for dual-species ion traps, significantly speeding up the process.
- Why this is important: Inadequacies in current quantum processor cooling methods create performance bottlenecks due to the necessity of intermediate cooling using ions of another species.
- What the research proposes: Introduce a bank of ‘coolant’ ions which are laser cooled. Computational ions are cooled by proximity to these coolant ions, allowing for a single-species approach.
- Results: Achieved exchange cooling in 107 $\mu s$, an order of magnitude faster than traditional methods, with over 96% of axial motional energy removed from the computational ion without decohering it.
