Detecting the entanglement of vortices in ultracold bosons with artificial gauge fields
Li Dai, Lin Xia, Lin Zhuang +1
The entanglement of vortices in a two-dimensional Bose-Hubbard model with artificial gauge fields is investigated using the exact diagonalization techniques. We propose an effectiv…
Entanglement convertibility by sweeping through the quantum phases of the alternating bonds chain
Yu-Chin Tzeng, Li Dai, M. -C. Chung +2
We study the entanglement structure and the topological edge states of the ground state of the spin-1/2 XXZ model with bond alternation. We employ parity-density matrix renormaliza…
Breakdown of local convertibility through Majorana modes in a quantum quench
Li Dai, Ming-Chiang Chung
The local convertibility of quantum states, measured by the Rényi entropy, is concerned with whether or not a state can be transformed into another state, using only local operatio…
Extracting entangled qubits from Majorana fermions in quantum dot chains through the measurement of parity
Li Dai, Watson Kuo, Ming-Chiang Chung
We propose a scheme for extracting entangled charge qubits from quantum-dot chains that support zero-energy edge modes. The edge mode is composed of Majorana fermions localized at…
Correlations and thermalization in driven cavity arrays
Li Dai, Dimitris G. Angelakis, Leong Chuan Kwek +1
We show that long-distance steady-state quantum correlations (entanglement) between pairs of cavity-atom systems in an array of lossy and driven coupled resonators can be establish…
Coherent control of long-distance steady state entanglement in lossy resonator arrays
Dimitris G. Angelakis, Li Dai, Leong-Chuan Kwek
We show that coherent control of the steady-state long-distance entanglement between pairs of cavity-atom systems in an array of lossy and driven coupled resonators is possible. Th…
