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…

Topological phase transition of deformed $Z_{3}$ toric code

Yun-Tak Oh, Hyun-Yong Lee

We investigate topological phase transitions in a family of deformed $Z_{3}$ toric-code wavefunctions prepared from a cluster state by local deformations and projective measu…
