Benincasa-Dowker-Glaser causal set actions by quantum counting
Sean A. Adamson, Petros Wallden
Causal set theory is an approach to quantum gravity in which spacetime is fundamentally discrete while retaining local Lorentz invariance. The Benincasa-Dowker-Glaser action is the…

Adiabatic quantum unstructured search in parallel
Sean A. Adamson, Petros Wallden
We present an optimized adiabatic quantum schedule for unstructured search building on the original approach of Roland and Cerf [Phys. Rev. A 65, 042308 (2002)]. Our schedule adiab…

Quantum Magic Rectangles: Characterization and Application to Certified Randomness Expansion
Sean A. Adamson, Petros Wallden
We study a generalization of the Mermin-Peres magic square game to arbitrary rectangular dimensions. After exhibiting some general properties, these rectangular games are fully cha…
