Identifying vulnerable nodes and detecting malicious entanglement patterns to handle st-connectivity attacks in quantum networks
Iain Burge, Michel Barbeau, Joaquin Garcia-Alfaro
Several problems in distributed system security naturally map to graphs. The concept of centrality assesses the importance of nodes in a graph. It is used in various applications.…
Quantum CORDIC -- Arcsine on a Budget
Iain Burge, Michel Barbeau, Joaquin Garcia-Alfaro
This work introduces a quantum algorithm for computing the function arcsine, with arbitrary accuracy. We leverage a technique from embedded computing and field-programmable gate ar…
A Shapley Value Estimation Speedup for Efficient Explainable Quantum AI
Iain Burge, Michel Barbeau, Joaquin Garcia-Alfaro
This work focuses on developing efficient post-hoc explanations for quantum AI algorithms. In classical contexts, the cooperative game theory concept of the Shapley value adapts na…
A Quantum Algorithm for Shapley Value Estimation
Iain Burge, Michel Barbeau, Joaquin Garcia-Alfaro
In the classical context, the cooperative game theory concept of the Shapley value has been adapted for post hoc explanations of machine learning models. However, this approach doe…
