Speeding up entanglement generation by proximity to higher-order exceptional points
Zeng-Zhao Li, Weijian Chen, Maryam Abbasi +2
Entanglement is a key resource for quantum information technologies ranging from quantum sensing to quantum computing. Conventionally, the entanglement between two coupled qubits i…
Topological quantum interference in a pumped Su-Schrieffer-Heeger lattice
Zeng-Zhao Li, Juan Atalaya, K. Birgitta Whaley
Topological quantum interference emerges from the interplay between quantum mechanics and topology. We present evidence for two types of such interference phenomenon that can resul…
Unraveling excitation energy transfer assisted by collective behaviors of vibrations
Zeng-Zhao Li, Liwen Ko, Zhibo Yang +2
We investigate how collective behaviors of vibrations such as cooperativity and interference can enhance energy transfer in a nontrivial way, focusing on an example of a donor-brid…
Probing weak dipole-dipole interaction using phase-modulated non-linear spectroscopy
Zeng-Zhao Li, Lukas Bruder, Frank Stienkemeier +1
Phase-modulated non-linear spectroscopy with higher harmonic demodulation has recently been suggested to provide information on many-body excitations. In the present work we theore…
Approach to solving spin-boson dynamics via non-Markovian quantum trajectories
Zeng-Zhao Li, Cho-Tung Yip, Hai-Yao Deng +4
We develop a systematic and efficient approach for numerically solving the non-Markovian quantum state diffusion equations for open quantum systems coupled to an environment up to…
Probing zero-modes of defect in Kitaev quantum wire
Sheng-Wen Li, Zeng-Zhao Li, C. Y. Cai +1
The Kitaev quantum wire (KQW) model with open boundary possesses two Majorana edge modes. When the local chemical potential on a defect site is much higher than that on other sites…
Study of the decoherence of a double quantum dot charge qubit via the Redfield equation
Zeng-Zhao Li, Xiao-Yin Pan, Xian-Ting Liang
By using the Redfield form of the master equation, we investigate the decoherence times of a double quantum dot charge qubit (DQDCQ) in three different cases, namely when it is cou…
