Indirect control with quantum accessor: coherent control by initial state preparation
H. Dong, X. F. Liu, H. C. Fu +1
This is the second one in our series of papers on indirect quantum control assisted by quantum accessor. In this paper we propose and study a new class of indirect quantum control(…
Quantum theory for spatial motion of polaritons in inhomogeneous fields
Lan Zhou, Jing Lu, D. L. Zhou +1
Polaritons are the collective excitations of many atoms dressed by resonant photons, which can be used to explain the slow light propagation with the mechanism of electromagnetical…
Disentanglement in a quantum critical environment
Zhe Sun, Xiaoguang Wang, C. P. Sun
We study the dynamical process of disentanglement of two qubits and two qutrits coupled to an Ising spin chain in a transverse field, which exhibits a quantum phase transition. We…
Quantum Critical Dynamics of A Qubit Coupled to An Isotropic Lipkin-Meshkov-Glick Bath
H. T. Quan, Z. D. Wang, C. P. Sun
We explore a dynamic signature of quantum phase transition (QPT) in an isotropic Lipkin-Meshkov-Glick (LMG) model by studying the time evolution of a central qubit coupled to it. W…
