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.
Bio: Eddie Schoute is a staff research scientist at IBM with a research focus on quantum compilation for fault-tolerant architectures and quantum algorithms. He has published algorithms for compilation to gross code and surface code architectures and on quantum routing for architectures with limited interactions. His current interest is to reduce resource requirements for quantum computation. Eddie completed a PostDoc at the Los Alamos National Laboratory and graduated with a computer science PhD from the University of Maryland, College Park.
