Remote Preparation of Mixed States via Noisy Entanglement

Guo-Yong Xiang, Jian Li, Bo Yu +1

We present a practical and general scheme of remote preparation for pure and mixed state, in which an auxiliary qubit and controlled-NOT gate are used. We discuss the remote state…

Scalable fault-tolerant quantum computation in DFS blocks

Zheng-Wei Zhou, Bo Yu, Xingxiang Zhou +2

We investigate how to concatenate different decoherence-free subspaces (DFSs) to realize scalable universal fault-tolerant quantum computation. Based on tunable interactions,…

Robust high-fidelity teleportation of an atomic state through the detection of cavity decay

Bo Yu, Zheng-Wei Zhou, Yong Zhang +2

We propose a scheme for quantum teleportation of an atomic state based on the detection of cavity decay. The internal state of an atom trapped in a cavity can be disembodiedly tran…

Concatenating dynamical decoupling with decoherence-free subspaces for quantum computation

Yong Zhang, Zheng-Wei Zhou, Bo Yu +1

A scheme to implement a quantum computer subjected to decoherence and governed by an untunable qubit-qubit interaction is presented. By concatenating dynamical decoupling through b…

Orbital angular momentum of the down converted photons

Xi-Feng Ren, Guo-Ping Guo, Bo Yu +2

We calculate the relative amplitude of orbital angular momentum (OAM) entangled photon pairs from the spontaneous parametric down conversion. The results show that the amplitude de…
