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…
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…
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…
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…
Operating two exchange-only qubits in parallel
Mateusz T. MÄ dzik, Florian Luthi, Gian Giacomo Guerreschi +38
