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…
Hyperparallel transistor, router and dynamic random access memory with unity fidelities
Ji-Zhen Liu, Ning-Yang Chen, Wen-Qiang Liu +2
We theoretically implement some hyperparallel optical elements, including quantum single photon transistor, router, and dynamic random access memory (DRAM). The inevitable side lea…
Low-cost Fredkin gate with auxiliary space
Wen-Qiang Liu, Hai-Rui Wei, Leong-Chuan Kwek
Effective quantum information processing is tantamount in part to the minimization the quantum resources needed by quantum logic gates. Here, we propose an optimization of an n-con…
Efficient Fusion of Photonic W-states with Nonunitary Partial-swap Gates
Hai-Rui Wei, Wen-Qiang Liu, Leong-Chuan Kwek
We introduce a nonunitary partial-swap gate for fusing arbitrary small-sized photonic W-states into a large-scale entangled network of W-state efficiently without ancillary photons…
