Control excitation and coherent transfer in a dimer
Hong-rong Li, Pei Zhang, Yingjun Liu +2
In this article, the processes of energy absorption and coherent transfer in a dimer is studied. The dimer includes two two-level pigments --- donor and acceptor, where donor is as…
Implementing the Deutsch's algorithm with spin-orbital angular momentum of photon without interferometer
Pei Zhang, Yan Jiang, Rui-Feng Liu +3
Deutsch's algorithm is the simplest quantum algorithm which shows the acceleration of quantum computer. In this paper, we theoretically advance a scheme to implement quantum Deutsc…
Implementation of one-dimensional quantum walks on spin-orbital angular momentum space of photons
Pei Zhang, Bi-Heng Liu, Rui-Feng Liu +3
Photons can carry spin angular momentum (SAM) and orbital angular momentum (OAM), which can be used to realize a qubit system and a high-dimension system respectively. This spin-or…
Entanglement distillation from Gaussian input states by coherent photon addition
Pei Zhang, Hong-Rong Li, Hong Gao +1
The entanglement between Gaussian entangled states can be increased by non-Gaussian operations. We design a new scheme named coherent photon addition, which can coherently add one…
