Eddie Schoute - Tour de gross: A modular quantum computer based on bivariate bicycle codes

Recorded 19 February 2026. Eddie Schoute of IBM Research presents "Tour de gross: A modular quantum computer based on bivariate bicycle codes" at IPAM's Bridging the Gap Between NISQ and FTQC Workshop.
Abstract: We present the bicycle architecture, a modular quantum computing framework based on high-rate, low-overhead quantum LDPC codes identified in prior work. For two specific bivariate bicycle codes with distances 12 and 18, we construct explicit fault-tolerant logical instruction sets and estimate the logical error rate of the instructions under circuit noise. We develop a compilation strategy adapted to the constraints of the bicycle architecture, enabling large-scale universal quantum circuit execution. Integrating these components, we perform end-to-end resource estimates demonstrating that an order of magnitude larger logical circuits can be implemented with a given number of physical qubits on the bicycle architecture than on surface code architectures. We anticipate further improvements through advances in code constructions, circuit designs, and compilation techniques.
