Entangled Telecom Photon Generation using Twisted Van der Waals Crystals
Nidhin Prasannan, Konstantinos Mourzidis, Vishwas Jindal +11
Nanoscale quantum light sources are essential building blocks for integrated quantum photonic systems. Here, we report a wavelength-scale entangled-photon source based on van der W…
Nonreciprocal magnon-magnon entanglement in a spinning cavity-magnon system
Zhisheng Xu, Mengxue Li, Chunfang Sun +1
Cavity-magnon systems, combining magnons and photons, offer a versatile platform for studying quantum entanglement and advancing quantum information science. In this work, we propo…
Optimizing the preparation of Dicke states using counterdiabatic driving methods
Fengzhe Tang, Gangcheng Wang
Recently, the technique of counterdiabatic driving, which provides an effective strategy for accelerating adiabatic quantum evolution, has been widely applied in the preparation of…
Magnonic entanglement in a chiral cavity-magnon coupling system
Yuxin Kang, Xin Zeng, Wuji Zhang +3
The generation of magnon entanglement and squeezing plays a crucial role in quantum information processing. In this study, we propose a scheme based on a chiral cavity-magnon syste…
Generation of high-fidelity Greenberger-Horne-Zeilinger states in a driven hybrid quantum system
Xin Zeng, Yuxin Kang, Chunfang Sun +2
In this study, we propose a theoretical scheme for achieving long-distance Greenberger-Horne-Zeilinger states in a driven hybrid quantum system. By applying a microwave field to th…
Protecting quantum gates from arbitrary single- and two-qubit errors
Chunfeng Wu, Gangcheng Wang, Xun-Li Feng
We explore the protection of quantum gates from arbitrary single- and two-qubit noises with properly designed dynamical decoupling pulses. The proposed dynamical decoupling method…
