About The Position

We are pioneering advancements in quantum computing by utilizing trapped ion technology and our proprietary laser-free quantum control methods. Our research and development efforts build on our fully integrated quantum processors that can be fabricated within standard silicon foundries. This unique approach allows us to leverage the highest-performing qubit technology while ensuring scalability and manufacturability using existing semiconductor fabrication technology. We approach quantum computing with a focus on minimizing errors, striving to achieve ultra-low gate errors at scale. Our immediate objective is to develop functional quantum computers within the NISQ regime, aiming to construct fault-tolerant machines that require minimal QEC overhead. Our recent breakthroughs include achieving 99.97% fidelity in two-qubit gates and 99.9992% fidelity in single-qubit operations without error correction, setting new industry standards for performance.
