Locally Acting Grover Mixers for Constraint-Preserving QAOA
Minjin Choi, Dongkeun Lee, Junghee Ryu
The Grover mixer quantum alternating operator ansatz (GM-QAOA) employs the Grover mixer to confine the quantum evolution to the feasible subspace defined by the problem. Its mixing…

Genuine monogamy relations in no-signaling theories - a geometric approach
Junghee Ryu, Daemin Lee, Jinhyoung Lee +2
Quantum correlations are subject to certain distribution rules represented by so-called monogamy relations. Derivation of monogamy relations for multipartite systems is a non-trivi…

Robustness measures for quantifying nonlocality
Kyunghyun Baek, Junghee Ryu, Jinhyoung Lee
We suggest generalized robustness for quantifying nonlocality and derive its equivalence to the maximum violation ratio of Bell inequalities defined as vectors with non-negative el…
