Borrowed Identities: Malleable Distillation Factories and a Unified Numerical Search
Shraddha Singh, Craig Gidney, Cody Jones
The paper proposes a weaker "borrowed-identity" condition for magic‑state distillation circuits, enabling a unified numerical search that discovers and combines various distillatio…
Securing Elliptic Curve Cryptocurrencies against Quantum Vulnerabilities: Resource Estimates and Mitigations
Ryan Babbush, Adam Zalcman, Craig Gidney +6
This whitepaper seeks to elucidate implications that the capabilities of developing quantum architectures have on blockchain vulnerabilities and mitigation strategies. First, we pr…
LUCI in the Surface Code with Dropouts
Dripto M. Debroy, Matt McEwen, Craig Gidney +2
Recently, usage of detecting regions facilitated the discovery of new circuits for fault-tolerantly implementing the surface code. Building on these ideas, we present LUCI, a frame…
Magic state cultivation on a superconducting quantum processor
Emma Rosenfeld, Craig Gidney, Gabrielle Roberts +292
Fault-tolerant quantum computing requires a universal gate set, but the necessary non-Clifford gates represent a significant resource cost for most quantum error correction archite…
Low Depth Color Code Circuits with CXSWAP gate
Satoshi Yoshida, Craig Gidney, Matt McEwen +1
We present two new types of syndrome extraction circuits for the color code. Our first construction, which after [M. McEwen, D. Bacon, and C. Gidney, Quantum 7, 1172 (2023)] we cal…
Verifiable Quantum Advantage via Optimized DQI Circuits
Tanuj Khattar, Noah Shutty, Craig Gidney +5
Decoded Quantum Interferometry (DQI) provides a framework for superpolynomial quantum speedups by reducing certain optimization problems to reversible decoding tasks. We apply DQI…
