Journal Club - Benchmarking a High-Fidelity Mixed-Species Entangling Gate

Explore a detailed discussion of the groundbreaking research on high-fidelity mixed-species entangling gates in this 57-minute APS Physics Journal Club session. Delve into the intricacies of ion traps, photonic links, and the innovative lightshift gate technique as the authors of the PRL paper "Benchmarking a high-fidelity mixed-species entangling gate" present their findings. Gain insights into the challenges and advantages of co-trapping, the significance of two-qubit gates, and the novel approaches used for benchmarking, including Interleaved Randomized Benchmarking and Gate Set Tomography. Moderated by Jonathan Home from ETH Zürich, this session offers a comprehensive overview of the research, its implications, and potential future milestones in the field of quantum computing and mixed-species entanglement.
