Quantum block encoding for one-pair semiseparable matrices
Giacomo Antonioli, Paola Boito, Gianna M. Del Corso +1
Quantum block encoding (QBE) is a crucial step in the development of most quantum algorithms, as it provides an embedding of a given matrix into a suitable larger unitary matrix. H…

Quantum Hitting Time according to a given distribution
P. Boito, G. M. Del Corso
In this work we focus on the notion of quantum hitting time for discrete-time Szegedy quantum walks, compared to its classical counterpart. Under suitable hypotheses, quantum hitti…

Ranking nodes in directed networks via continuous-time quantum walks
Paola Boito, Roberto Grena
Four new centrality measures for directed networks based on unitary, continuous-time quantum walks (CTQW) in dimensions -- where is the number of nodes -- are presented, te…
