Snakes and Ladders: Adapting the surface code to defects
Catherine Leroux, Sophia F. Lin, Przemyslaw Bienias +4
One of the critical challenges solid-state quantum processors face is the presence of fabrication imperfections and two-level systems, which render certain qubits and gates either…
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…
Spatially parallel decoding for multi-qubit lattice surgery
Sophia Fuhui Lin, Eric C. Peterson, Krishanu Sankar +1
Running quantum algorithms protected by quantum error correction requires a real time, classical decoder. To prevent the accumulation of a backlog, this decoder must process syndro…
qSIEVE: Efficient qLDPC Memory via Systolic Movement in Atom Arrays
Joshua Viszlai, Willers Yang, Sophia Fuhui Lin +4
As quantum machines have scaled up in their number of qubits, significant research has turned towards increasing their fidelity with quantum error correction codes. Although promis…
An Architecture for Improved Surface Code Connectivity in Neutral Atoms
Joshua Viszlai, Sophia Fuhui Lin, Siddharth Dangwal +2
In order to achieve error rates necessary for advantageous quantum algorithms, Quantum Error Correction (QEC) will need to be employed, improving logical qubit fidelity beyond what…
Microarchitectures for Heterogeneous Superconducting Quantum Computers
Samuel Stein, Sara Sussman, Teague Tomesh +12
Noisy Intermediate-Scale Quantum Computing (NISQ) has dominated headlines in recent years, with the longer-term vision of Fault-Tolerant Quantum Computation (FTQC) offering signifi…
Codesign of quantum error-correcting codes and modular chiplets in the presence of defects
Sophia Fuhui Lin, Joshua Viszlai, Kaitlin N. Smith +4
Fabrication errors pose a significant challenge in scaling up solid-state quantum devices to the sizes required for fault-tolerant (FT) quantum applications. To mitigate the resour…
Algorithms for perturbative analysis and simulation of quantum dynamics
Daniel Puzzuoli, Sophia Fuhui Lin, Moein Malekakhlagh +3

Let Each Quantum Bit Choose Its Basis Gates
Sophia Fuhui Lin, Sara Sussman, Casey Duckering +5
Near-term quantum computers are primarily limited by errors in quantum operations (or gates) between two quantum bits (or qubits). A physical machine typically provides a set of ba…
Better Than Worst-Case Decoding for Quantum Error Correction
Gokul Subramanian Ravi, Jonathan M. Baker, Arash Fayyazi +4
The overheads of classical decoding for quantum error correction on superconducting quantum systems grow rapidly with the number of logical qubits and their correction code distanc…
Systematic Crosstalk Mitigation for Superconducting Qubits via Frequency-Aware Compilation
Yongshan Ding, Pranav Gokhale, Sophia Fuhui Lin +3
One of the key challenges in current Noisy Intermediate-Scale Quantum (NISQ) computers is to control a quantum system with high-fidelity quantum gates. There are many reasons a qua…
