Deterministic Preparation of Arbitrary Spin Eigenfunctions
Wenxuan Tao, Jianan Wang, Fen Zuo
Quantum states with conserved total spins, or spin eigenfunctions, are important for studying quantum chemistry and quantum manybody physics problems. A typical class of spin eigen…
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…
