Constructing locally indistinguishable orthogonal product bases in an system
Guang-Bao Xu, Ying-Hui Yang, Qiao-Yan Wen +2
Recently, Zhang et al [Phys. Rev. A 92, 012332 (2015)] presented orthogonal product states that are locally indistinguishable and completable in a quantum syste…
QKD-based quantum private query without a failure probability
Bin Liu, Fei Gao, Wei Huang +1
In this paper, we present a quantum-key-distribution (QKD)-based quantum private query (QPQ) protocol utilizing single-photon signal of multiple optical pulses. It maintains the ad…
Local indistinguishability of orthogonal product states
Zhi-Chao Zhang, Fei Gao, Ya Cao +2
In the general bipartite quantum system , Wang \emph{et al.} [Y.-L Wang \emph{et al.}, Phys. Rev. A \textbf{92}, 032313 (2015)] presented orthogonal product…
Generic Quantum Walks with Memory
Dan Li, Michael Mc Gettrick, Fei Gao +2
Quantum walks with memory(QWM) are a type of modified quantum walks that record the walker's latest path. As we know, only two kinds of QWM are presented up to now. It is desired t…
Semi-device-independent randomness expansion with partially free random sources
Yu-Qian Zhou, Hong-Wei Li, Yu-Kun Wang +3
By proposing device-independent protocols, S. Pironio et al. [Nature 464, 1021-1024 (2010)] and R. Colbeck et al. [Nature Physics 8, 450-453 (2012)] proved that new randomness can…
Determination of stabilizer states
Xia Wu, Ying-hui Yang, Yu-kun Wang +3
The determination of many special types of quantum states has been studied thoroughly, such as the generalized |GHZ> states, |W> states equivalent under stochastic local operations…
