Abstract:

Quantum computers represent a new computing paradigm and have the potential to serve as a disruptive tool for scientific discovery and practical applications. However, they face the fundamental challenges of errors and decoherence. Quantum error correction (QEC) and fault-tolerant quantum computation (FTQC) are therefore crucial for realizing the promise of quantum computing. In this talk, I will describe how recent experimental and theoretical advances motivate new architectures for fault-tolerant quantum computers. I will first present our realization of early-FT logical algorithms and key building blocks of large-scale universal FTQC in neutral atom quantum computers. Motivated by these emerging capabilities of hardware architectures, I will then describe how theoretical advances, such as quantum low-density parity-check codes and improved fault tolerance constructions, can enable drastic reductions in the space and time overhead of FTQC. Altogether, this co-design of hardware architecture, quantum error correction, and quantum algorithms represents a promising path to architecting utility-scale quantum computers.

Biography:

Hengyun (Harry) Zhou is the Quantum Error Correction Architecture Lead at QuEra Computing. His PhD work from Prof. Mikhail Lukin’s group at Harvard made key contributions to quantum sensing and quantum many-body physics, recognized as a finalist for the American Physical Society’s (APS) Division of Atomic, Molecular and Optical Physics (DAMOP) thesis prize. His recent work focuses on novel fault-tolerant architectures for neutral atom quantum computers, by co-designing hardware architecture, quantum error correction, and quantum algorithm compilation, with promise to drastically reduce the requirements for building large-scale quantum computers.
