Time rescaling for second-order feedback-based quantum optimization
Leticia Bertuzzi, João P. Engster, Evandro C. R. da Rosa +1
Feedback-based quantum algorithms recently gained attention by demonstrating how quantum computers can be used to solve optimization problems without resorting to hybrid quantum-cl…
Global Entanglement Quantification via Classical Shadows
João P. Engster, Eduardo I. Duzzioni
Detecting and characterizing quantum correlations are tasks of great relevance in quantum information. More specifically, quantifying the amount of multipartite entanglement is a k…
Quantum Approximate Multi-Objective Optimization in Routing Problems
Eduardo Willwock Lussi, Alisson dos Passos Fumaco, Marcos Vinicius Reballo +3
Multi-objective optimization (MOO) problems are common in logistics, where routing decisions must balance conflicting objectives such as travel distance, delivery time, and operati…
Evaluating Parameter Transfer in FALQON Across Graph Families
Alisson dos Passos Fumaco, Marcos Vinicius Reballo, Fernando Augusto Caletti de Barros +2
We evaluate FALQON parameter transfer for Max-Cut, transferring sequences from small donors () to 14-node recipients. Using 3-regular and Erdős-Rényi families, w…
Continuous-time quantum walks on a defective lattice: Boosting the spreading of delocalized states through Parrondo's strategy
João V. Cordeiro, Eduardo I. Duzzioni, Edgard P. M. Amorim
We investigate the quantum transport of delocalized states in continuous-time quantum walks (CTQWs) on a one-dimensional lattice containing a single defect. The defect is modeled b…
Optimizing Quantum Compilation via High-Level Quantum Instructions
Evandro C. R. Rosa, Jerusa Marchi, Eduardo I. Duzzioni +1
Current quantum programming is dominated by low-level, circuit-centric approaches that limit the potential for compiler optimization. This work presents how a high-level programmin…
Full Quantum Stack: Ket Platform
Evandro Rosa, Eduardo Lussi, Jerusa Marchi +1
As quantum computing hardware continues to scale, the need for a robust software infrastructure that bridges the gap between high-level algorithm development and low-level physical…
