CAbLECAR: efficiently scheduling QLDPC codes on a tileable spin qubit chip with shuttling
Jason D. Chadwick, Frederic T. Chong
Semiconductor spin qubits are a promising platform for large-scale quantum computing, but have yet to take full advantage of the broad class of quantum low-density parity check (QL…
Spacetime-Efficient and Hardware-Compatible Complex Quantum Logic Units in qLDPC Codes
Willers Yang, Jason Chadwick, Mariesa H. Teo +2
Quantum low-density parity-check (qLDPC) codes offer a promising route to scalable fault-tolerant quantum computing due to their substantially reduced footprint. However, these gai…
ReloQate: Transient Drift Detection and In-Situ Recalibration in Surface Code Quantum Error Correction
Maxwell Poster, Jason Chadwick, Jonathan Mark Baker
Quantum error correction (QEC) promises to exponentially suppress qubit noise, but typically assumes spatially-uniform and temporally-constant noise rates. However, real quantum ha…
A manufacturable surface code architecture for spin qubits with fast transversal logic
Jason D. Chadwick, Willers Yang, Joshua Viszlai +1
Spin qubits in silicon quantum dot arrays are a promising quantum computation platform for long-term scalability due to their small qubit footprint and compatibility with advanced…

Predictive Window Decoding for Fault-Tolerant Quantum Programs
Joshua Viszlai, Jason D. Chadwick, Sarang Joshi +3
Real-time decoding is a key ingredient in future fault-tolerant quantum systems, yet many decoders are too slow to run in real time. Prior work has shown that parallel window decod…
Short two-qubit pulse sequences for exchange-only spin qubits in 2D layouts
Jason D. Chadwick, Gian Giacomo Guerreschi, Florian Luthi +9
Exchange-only (EO) spin qubits in quantum dots offer an expansive design landscape for architecting scalable device layouts. The study of two-EO-qubit operations, which involve six…
Averting multi-qubit burst errors in surface code magic state factories
Jason D. Chadwick, Christopher Kang, Joshua Viszlai +2
Fault-tolerant quantum computation relies on the assumption of time-invariant, sufficiently low physical error rates. However, current superconducting quantum computers suffer from…
Qompress: Efficient Compilation for Ququarts Exploiting Partial and Mixed Radix Operations for Communication Reduction
Andrew Litteken, Lennart Maximilian Seifert, Jason Chadwick +3
Quantum computing is in an era of limited resources. Current hardware lacks high fidelity gates, long coherence times, and the number of computational units required to perform mea…
Dancing the Quantum Waltz: Compiling Three-Qubit Gates on Four Level Architectures
Andrew Litteken, Lennart Maximilian Seifert, Jason D. Chadwick +6
Superconducting quantum devices are a leading technology for quantum computation, but they suffer from several challenges. Gate errors, coherence errors and a lack of connectivity…
