Repeat-Until-Success Generation of Symmetric States without External Control
Qing Chen, Jianhua Cheng, Ke-Lin Wang +1
In the present paper, we propose a "repeat-until-success" scheme induced by single particle measurement to generate arbitrary symmetric states based on spin network. This protocol…

Optimal quantum cloning via spin networks
Qing Chen, Jianhua Cheng, Ke-Lin Wang +1
In this paper we present an approach to quantum cloning via free dynamical evolution of spin networks. By properly designing the network and the couplings between spins, we show th…

Efficient construction of 2-D cluster states with probabilistic quantum gates
Qing Chen, Jianhua Cheng, Ke-Lin Wang +1
We propose an efficient scheme for constructing arbitrary 2-D cluster states using probabilistic entangling quantum gates.In our scheme, the 2-D cluster state is constructed with s…
