Spectral signatures of nonstabilizerness and criticality in infinite matrix product states
Andrew Hallam, Ryan Smith, Zlatko PapiÄ
The paper introduces a spectral transfer‑matrix method to study the stabilizer Rényi entropy in infinite matrix product states, revealing a distinct correlation length that diverge…

Robust Quantum Sensing via Prethermal Spin Orbits
Enrico Daniel Richter, Ryan J. Smith, Brayden Glockzin +3
Practical performance of quantum sensors is often curtailed by uncontrolled environmental drift (bias-field instability, temperature fluctuations, mechanical vibration), background…

Non-stabilizerness in kinetically-constrained Rydberg atom arrays
Ryan Smith, Zlatko PapiÄ, Andrew Hallam
Non-stabilizer states are a fundamental resource for universal quantum computation. However,despite broad significance in quantum computing, the emergence of "many-body" non-stabil…
