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…
Robust-fidelity hyperparallel controlled-phase-flip gate through microcavities
Hai-Rui Wei, Yan-Bei Zheng, Ming Hua +1
Hyperparallel quantum information processing outperforms its traditional parallel one in terms of channel capacity, low loss rate, and processing speed. We present a way for implem…
Optimal synthesis of the Fredkin gate in a multilevel system
Wen-Qiang Liu, Hai-Rui Wei
The optimal cost of a three-qubit Fredkin gate is 5 two-qubit entangling gates, and the overhead climbs to 8 when restricted to controlled-not (CNOT) gates. By harnessing higher-di…
Implementing two-photon three-degree-of-freedom hyper-parallel controlled phase flip gate through cavity-assisted interactions
Hai-Rui Wei, Wen-Qiang Liu, Ning-Yang Chen
Hyper-parallel quantum information processing is a promising and beneficial research field. In this paper, we present a method to implement a hyper-parallel controlled-phase-flip (…
Implementations of more general solid-state (SWAP) and controlled-(swap) gates
Wen-Qiang Liu, Hai-Rui Wei
Universal quantum gates are the core elements in quantum information processing. We design two schemes to realize more general (SWAP) and controlled--(swap) gates (…
