Floquet Prethermal Phase Protected by U(1) Symmetry on a Superconducting Quantum Processor
Chong Ying, Qihao Guo, Shaowei Li +22
Periodically driven systems, or Floquet systems, exhibit many novel dynamics and interesting out-of-equilibrium phases of matter. Those phases arising with the quantum systems' sym…
Simplified scheme for entanglement preparation with Rydberg pumping via dissipation
Shi-Lei Su, Qi Guo, Hong-Fu Wang +1
Inspired by recent work [A. W. Carr and M. Saffman, Phys. Rev. Lett. 111, 033607 (2013)], we propose a simplified scheme to prepare the two-atom maximally entangled states via diss…
High-efficiency alignment-free quantum cryptography based on quantum interference
Qi Guo, Liu-Yong Cheng, Hong-Fu Wang +1
We propose an alternative quantum cryptography protocol using the quantum interference effect. The efficiency of creating sifted key can reach 100\% in principle, which is higher t…
Preparation of entanglement between atoms in spatially separated cavities via fiber loss
Shi-Lei Su, Xiao-Qiang Shao, Qi Guo +3
We propose a scheme to prepare a maximally entangled state for two Lambda-type atoms trapped in separate optical cavities coupled through an optical fiber based on the combined eff…
Counterfactual quantum-information transfer
Qi Guo, Liu-Yong Cheng, Li Chen +2
We demonstrate quantum information can be transferred between two distant participants without any physical particles travelling between them. The key procedure of the counterfactu…
Simple implementation of quantum delayed-choice experiment using conventional linear optical elements
Qi Guo, Liu-Yong Cheng, Hong-Fu Wang +1
We propose a simple implementation scheme of quantum delayed-choice experiment in linear optical system without initial entanglement resource. By choosing different detecting devic…
