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…
Shadow measurements for feedback-based quantum optimization
Leticia Bertuzzi, João P. Engster, Evandro C. R. da Rosa +1
Improving the performance of quantum algorithms is a fundamental task to achieve quantum advantage. In many cases, extracting information from quantum systems poses an important ch…
High-fidelity state transfer via quantum walks from delocalized states
João P. Engster, Rafael Vieira, Eduardo I. Duzzioni +1
We study the state transfer through quantum walks placed on a bounded one-dimensional path. We first consider continuous-time quantum walks from a Gaussian state. We find such a st…
