Covariant feedback Control of arbitrary qudit state against Depolarizing Noise is impossible
ShengLi Zhang, XuBo Zou, Chuanfeng Li +2
In this paper, we prove that it is impossible to construct a convariant quantum feedback control instruments which aim to correct the channel noise imposed on an unknown qubit. The…
Influence of configuration and acoustic phonons on three-qubit controlled-phase gate
Song Yang, Ming Gong, Xubo Zou +3
We discuss the configuration and acoustic phonon effect on the conditional phase gate using self assembled quantum dots. As an example, we discuss the simplest three dots condition…
Closing the gap of secure quantum key rate with the Heralded Pair-Coherent States
ShengLi Zhang, XuBo Zou, ChenHui Jin +1
In this paper, we investigate the long-standing gap of quantum key rate between the Weak Coherent Pulse (WCP) and Heralded Single Photon Sources(HSPS) implementation of quantum cry…
Frequency-up conversion and quantum swap gate in an optical cavity with atomic cloud
Gong-Wei Lin, Xu-Bo Zou, Ming-Yong Ye +2
A scheme is presented for realizing frequency-up conversion and a two-qubit quantum swap gate for intracavity fields. In the scheme, a V-type atomic ensemble prepared in their grou…
