Reachability Constraints in Variational Quantum Circuits: Optimization within Polynomial Group Module
Yun-Tak Oh, Dongsoo Lee, Jungyoul Park +2
This work identifies a necessary condition for any variational quantum approach to reach the exact ground state. Briefly, the norms of the projections of the input and the ground s…

Quantum Circuit Optimization by Graph Coloring
Hochang Lee, Kyung Chul Jeong, Panjin Kim
This work shows that minimizing the depth of a quantum circuit composed of commuting operations reduces to a vertex coloring problem on an appropriately constructed graph, where ga…
