Training-Free Certified Bounds for Quantum Regression: A Scalable Framework
Demerson N. Gonçalves, Tharso D. Fernandes, Pedro H. G. Lugao +1
We present a training-free, certified error bound for quantum regression derived directly from Pauli expectation values. Generalizing the heuristic of minimum accuracy from classif…

New Algorithm for Structured OFDM Channel Estimation using Subgroup Duality
Demerson N. Gonçalves, João T. Dias
This paper presents a group-theoretic framework for structured channel estimation in Orthogonal Frequency Division Multiplexing (OFDM). By modeling subcarriers as the cyclic group…
