Abstract:
Fault-tolerant quantum computation (FTQC) is a major goal of quantum information science, as it allows reliable manipulation of quantum information in the presence of noise and errors. In this talk, I will provide an overview of the main challenges and methods for achieving FTQC, such as quantum error correction (QEC), transversal and non-transversal logical gates, and their implications for universality. I will then focus on the specific advantages and opportunities of Rydberg atom arrays as a platform for FTQC, and show how their unique features, such as non-local connectivity, parallel gate action, collective mobility, and native multi-controlled-Z gates, can be used to implement a universal set of gates efficiently and robustly, through techniques like magic state distillation, concatenated code arrays and FT multi-controlled-Z codes (https://arxiv.org/abs/2312.09111)
