Explore a groundbreaking modular quantum computing framework in this 43-minute conference talk by Eddie Schoute from IBM Research. Discover the bicycle architecture, built on high-rate, low-overhead quantum LDPC codes that promise significant improvements over traditional surface code architectures. Learn about the construction of explicit fault-tolerant logical instruction sets for two specific bivariate bicycle codes with distances 12 and 18, and examine logical error rate estimates under circuit noise conditions. Understand the specialized compilation strategy developed for the bicycle architecture's constraints, enabling large-scale universal quantum circuit execution. Analyze comprehensive end-to-end resource estimates demonstrating how this architecture can implement logical circuits an order of magnitude larger than surface code architectures using the same number of physical qubits. Gain insights into the potential for further improvements through advances in code constructions, circuit designs, and compilation techniques, positioning this work at the forefront of bridging NISQ and fault-tolerant quantum computing paradigms.
