A matching decoder for bivariate bicycle codes
Kaavya Sahay, Dominic J. Williamson, Benjamin J. Brown
The discovery of new quantum error-correcting codes that encode several logical qubits into relatively few physical qubits motivates the development of efficient and accurate metho…
Architecting Early Fault Tolerant Neutral Atoms Systems with Quantum Advantage
Sahil Khan, Sayam Sethi, Kaavya Sahay +6
Recent advancements in neutral atom platforms have enabled exploration of early fault-tolerant (FT) architectures for applications with quantum advantage, such as quantum dynamics…
Fold-transversal surface code cultivation
Kaavya Sahay, Pei-Kai Tsai, Kathleen Chang +4
Magic state cultivation is a state-of-the-art protocol to prepare ultra-high fidelity non-Clifford resource states for universal quantum computation. It offers a significant reduct…
Minimising surface-code failures using a color-code decoder
Asmae Benhemou, Kaavya Sahay, Lingling Lao +1
The development of practical, high-performance decoding algorithms reduces the resource cost of fault-tolerant quantum computing. Here we propose a decoder for the surface code tha…
Error correction of transversal CNOT gates for scalable surface code computation
Kaavya Sahay, Yingjia Lin, Shilin Huang +2
Recent experimental advances have made it possible to implement logical multi-qubit transversal gates on surface codes in a multitude of platforms. A transversal controlled-NOT (tC…
Surface Code with Imperfect Erasure Checks
Kathleen Chang, Shraddha Singh, Jahan Claes +3
Recently, a lot of effort has been devoted towards designing erasure qubits in which dominant physical noise excites leakage states whose population can be detected and returned to…
