Testing APS conjecture on regular graphs
Wenxuan Tao, Fen Zuo
The maximum energy of the EPR model on a weighted graph is known to be upper-bounded by the sum of the total weight and the value of maximum-weight fractional matching~(MWFM). Rece…

A Refined Algorithm For the EPR model
Wenxuan Tao, Fen Zuo
The Einstein-Podolsky-Rosen~(EPR) model is an analogous model of the anti-ferromagnetic Heisenberg model or the equivalent quantum maximum-cut problem, proposed by R. King two year…

Improving stabilizer approximation with quantum strategy
Fen Zuo
We introduce a quantum strategy from nonlocal games to improve the stabilizer approximation we proposed previously. The resulting approach turns out to be a qubit-by-qubit gauging…
