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…
In-Situ Simultaneous Magic State Injection on Arbitrary CSS qLDPC Codes
Kun Liu, Shifan Xu, Tomas Jochym-O'Connor +3
Quantum low-density parity-check (qLDPC) codes can encode many logical qubits within a single code block at low physical qubit overhead, yet magic state injection into such codes r…
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…
Non-Abelian Quantum Signal Processing: A Composite Pulse for Fast Analytic Control of Hybrid Oscillator-Qubit Processors
Shraddha Singh, Baptiste Royer, Steven M. Girvin
Quantum Signal Processing (QSP) transforms a unitary parameterized by a classical variable into one governed by a polynomial function . Though quantum mechanics is line…
Hybrid Oscillator-Qubit Quantum Processors: Instruction Set Architectures, Abstract Machine Models, and Applications
Yuan Liu, Shraddha Singh, Kevin C. Smith +11
Quantum computing with discrete variable (DV, qubit) hardware is approaching the large scales necessary for computations beyond the reach of classical computers. However, important…
Fault-tolerant Fusion-based Quantum Computing with the Four-legged Cat Code
Harshvardhan K. Babla, James D. Teoh, Jahan Claes +4
The four-legged cat code is a quantum error-correcting code designed to address the predominant error in bosonic modes: single-photon loss. It was the first such code to surpass th…
