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…
Certified Lower Bounds and Efficient Estimation of Minimum Accuracy in Quantum Kernel Methods
Demerson N. Gonçalves, Tharso D. Fernandes, Andrias M. M. Cordeiro +2
The minimum accuracy heuristic evaluates quantum feature maps without requiring full quantum support vector machine (QSVM) training. However, the original formulation is computatio…
Quantum search by continuous-time quantum walk on t-designs
Pedro H. G. Lugão, Renato Portugal
This work examines the time complexity of quantum search algorithms on combinatorial -designs with multiple marked elements using the continuous-time quantum walk. Through a det…
Multimarked Spatial Search by Continuous-Time Quantum Walk
Pedro H. G. Lugão, Renato Portugal, Mohamed Sabri +1
The quantum-walk-based spatial search problem aims to find a marked vertex using a quantum walk on a graph with marked vertices. We describe a framework for determining the computa…
