Synthesis and upper bound of Schmidt rank of the bipartite controlled-unitary gates
Gui-Long Jiang, Hai-Rui Wei, Guo-Zhu Song +1
Quantum circuit model is the most popular paradigm for implementing complex quantum computation. Based on Cartan decomposition, we show that generalized controlled- (GC…
Linear optical universal quantum gates with higher success probabilities
Wen-Qiang Liu, Hai-Rui Wei
Universal quantum gates lie at the heart of designing quantum computer. We construct two compact quantum circuits to implement post-selected controlled-phase-flip (CPF) gate and To…
Deterministic and complete hyperentangled Bell states analysis assisted by frequency and time interval degrees of freedom
Xin-Jie Zhou, Wen-Qiang Liu, Hai-Rui Wei +2
Hyperentangled Bell states analysis (HBSA) is an essential building block for certain hyper-parallel quantum information processing. We propose a complete and deterministic HBSA sc…
Collective unitary evolution with linear optics by Cartan decomposition
Wen-Qiang Liu, Xin-Jie Zhou, Hai-Rui Wei
Unitary operation is an essential step for quantum information processing. We first propose an iterative procedure for decomposing a general unitary operation without resorting to…
Complete hyperentangled Bell states analysis for polarization-spatial-time-bin degrees of freedom with unity fidelity
Xin-Jie Zhou, Wen-Qiang Liu, Yan-Bei Zheng +2
Hyperentangled states can outperform their classical counterparts on solving certain tasks. Here we present a simplified scheme for completely distinguishing two-photon hyperentang…
