When Normalization Selects the Sign: Auditing Robustness Ablations in Quantum Attention
Owen Friedewald, Srikar Alla, Ali Shiri Sichani +1
Removing an input-scaling module changes both a classifier and the perturbations reaching its encoder. A robustness difference can therefore reflect the comparison rule as well as…
Where Quantum Fourier Sampling Stops Short: A Three-Gate Audit Protocol for Delay-PUF Security Models
Owen Friedewald, Ali Shiri Sichani, Chi-Ren Shyu
Quantum Fourier sampling may help audit the spectral learnability of delay-based physical unclonable functions (PUFs). We ask whether that promise survives access matching, a stron…
Exact Diagonal Completion on Reachable Subspaces: Application to QAOA Placement
Owen Friedewald, Ali Shiri Sichani, Chi-Ren Shyu
Unused encoding states offer opportunities to simplify quantum circuits. For algorithms restricted to reachable subspaces, unspecified diagonal-operator entries can be optimized wi…
Plateau-Constrained Selection: Exploiting Degeneracy for Lower-Depth Quantum Compilation
Owen Friedewald, Ali Shiri Sichani, Chi-Ren Shyu
Minimum-cost orders of commuting phase terms can produce substantially different routed circuits. On the same 36-term instances, three orders with identical support cost 74 yield m…
Shielded RL for Route-Charged Parity-Term Ordering in QEDA Phase Components
Owen Friedewald, Ali Shiri Sichani, Chi-Ren Shyu
Commuting phase terms in quantum electronic design automation (QEDA) placement circuits are logically invariant under reordering, yet their routed cost varies substantially after h…
