"Collisional quantum gates were proposed as a promising alternative for high-fidelity operations in both spin and charge degrees of freedom, demonstrating significant potential in quantum computing architectures."
"Using quantum gas microscopy, we determine both the continuous-time and discrete gate-based performance of the collisional interactions, achieving high entangling gate fidelities up to 99.75%."
"We generate entangled Bell states and observe noise-resilient entanglement with lifetimes exceeding 10 seconds, showcasing the robustness of collisional gates in quantum systems."
Collisional quantum gates have emerged as a viable alternative for quantum computing, particularly using fermionic 6Li atoms. These gates demonstrate high entangling fidelities, reaching up to 99.75%. Quantum gas microscopy has enhanced the characterization of these gates, allowing for the generation of entangled Bell states and observing entanglement with lifetimes over 10 seconds. The primary source of gate infidelity is linked to averaging over double-wells, highlighting the importance of precise control in quantum systems.
