Gap-Priced -States: Dynamic Post-Selection and Budget-Aware Factory Provisioning
Maxwell Poster, Sayam Sethi, Steven Hofmeyr +3
Magic -state preparation dominates the cost of fault-tolerant quantum computation on surface codes, yet cultivation and distillation are typically provisioned statically…
Staying Sober: A Shot-Free Predictor of Logical Error Rates for Concatenated Quantum Error Correcting Codes
Sayam Sethi, Aditi Awasthi, Maxwell Poster +2
Estimating the logical error rate (LER) of a quantum error-correcting (QEC) code by Monte Carlo sampling takes samples at physical error r…
Exploring Asymmetric QEC Code Concatenation
Sayam Sethi, Maxwell Poster, Aditi Awasthi +3
Concatenated quantum error-correcting codes have recently gained popularity because they improve the effective distance of a joint code without requiring the discovery of new codes…
Optimizing Logical Mappings for Quantum Low-Density Parity Check Codes
Sayam Sethi, Sahil Khan, Maxwell Poster +2
Early demonstrations of fault tolerant quantum systems have paved the way for logical-level compilation. For fault-tolerant applications to succeed, execution must finish with a lo…
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…
CQM: Cyclic Qubit Mappings
Maxwell Poster, Sayam Sethi, Jonathan Baker
Quantum computers show promise to solve select problems otherwise intractable on classical computers. However, noisy intermediate-scale quantum (NISQ) era devices are currently pro…
