Information scrambling and entanglement in quantum approximate optimization algorithm circuits
Chen Qian, Wei-Feng Zhuang, Rui-Cheng Guo +2
Variational quantum algorithms, which consist of optimal parameterized quantum circuits, are promising for demonstrating quantum advantages in the noisy intermediate-scale quantum…
Anti-Hong-Ou-Mandel interference by coherent perfect absorption of entangled photons
Anton N. Vetlugin, Ruixiang Guo, Cesare Soci +1
Two-photon interference, known as the Hong-Ou-Mandel effect, has colossal implications for quantum technology. It was observed in 1987 with two photodetectors monitoring outputs of…
Phase stabilization of a coherent fibre network by single-photon counting
Salih Yanikgonul, Ruixiang Guo, Angelos Xomalis +4
Coherent optical fibre networks are extremely sensitive to thermal, mechanical and acoustic noise, which requires elaborate schemes of phase stabilization with dedicated auxiliary…
Generation of concatenated Greenberger-Horne-Zeilinger-type entangled coherent state based on linear optics
Rui Guo, Lan Zhou, Shi-Pu Gu +2
The concatenated Greenberger-Horne-Zeilinger (C-GHZ) state is a new type of multipartite entangled state, which has potential application in future quantum information. In this pap…
Efficient -particle state concentration with different parity check gates
Yu-Bo Sheng, Lan Zhou, Yu-Wei Sheng +1
We present an universal way to concentrate an arbitrary -particle less-entangled state into a maximally entangled state with different parity check gates. It comprises t…
High momentum entanglement of cold atoms generated by a single photon scattering
Rui Guo, Xiaoji Zhou, Xuzong Chen
With the mechanism of pairwise scattering of photons between two atoms, we propose a novel scheme to highly entangle the motional state between two ultracold neutral atoms by a sin…
