As quantum hardware improves, quantum error correction has become feasible on some quantum devices. Although it is still too early to talk about fully fault-tolerant quantum computing, partial fault-tolerance can provide fruitful applications for scientists to explore. In this talk, I will introduce the basics of quantum computing and discuss why it is vital for us to be able to correct errors for scalable quantum computation. I will then discuss some of my work in quantum error detection and the Iceberg Code, which is a first step towards understanding how to compensate for noise in quantum computers. And finally, I will discuss our efforts to implement a partial quantum error correction method, called the Space-Time Efficient Analog Rotation (STAR) Architecture, on a neutral atom quantum computer that can avoid some of the most computationally expensive aspects of full fault-tolerance, while still correcting errors arising from Clifford gates.
Bio: I-Chi Chen is a PhD student and LANL GRA in his final year at Iowa State. His research lies at the intersection of quantum many-body dynamics, quantum simulation, and quantum computing. I-Chi participated in the 2024 Quantum Computing Summer School this past summer. I-Chi is a researcher in Tom Iadecola’s condensed matter physics group at Iowa State, where they have an excellent quantum physics program. I-Chi's publications include studies of 1) quantum dynamics of infinite-temperature energy transport; 2) a benchmark study of quantum computing hardware for the simulation of the dynamics of mixed-field Ising chains; 3) a study of the PXP model in a strong staggered external field, which manifests quasiparticle confinement; and 4) work on early fault-tolerant quantum computing with a LANL/QuEra collaboration. I-Chi received the 2021 IBM Open Science Prize for the task of the quantum simulation of the Heisenberg model. And he received first prize in Qhack 2024.
