Quantum correlations in topological quantum phase transitions
Yi-Xin Chen, Sheng-Wen Li
We study the quantum correlations in a 2D system that possesses a topological quantum phase transition. The quantumness of two-body correlations is measured by quantum discord. We…

Tunneling Qubit Operation on a Protected Josephson Junction Array
Zhi Yin, Sheng-Wen Li, Yi-Xin Chen
We discuss a protected quantum computation process based on a hexagon Josephson junction array. Qubits are encoded in the punctured array, which is topologically protected. The deg…
