Dressed-state scheme for a fast CNOT gate
Jin-Lei Wu, Xin Ji, Shou Zhang
A highly feasible dressed-state scheme, which greatly speeds up the adiabatic population transfer of a quantum system, is applied for implementing a fast CNOT gate in a cavity QED…
Fast adiabatic quantum state transfer and entanglement generation between two atoms via dressed states
Jin-Lei Wu, Xin Ji, Shou Zhang
Recently, a new method, which can significantly speed up adiabatic quantum state transfer by using dressed states, was proposed by Baksic \emph{et~al.} [Phys. Rev. Lett. \textbf{11…
Generation of genuine -type four-particle entangled state of superconducting artificial atoms with broken symmetry
Chun-Ling Leng, Qi Guo, Xin Ji +1
We propose a scheme for generating a genuine -type four-particle entangled state of superconducting artificial atoms with broken symmetry by using one-dimensional transmission l…
Shortcuts to adiabatic passage for multiqubit controlled phase gate
Yan Liang, Xin Ji
We propose an alternative scheme of shortcuts to quantum phase gate in a much shorter time based on the approach of Lewis-Riesenfeld invariants in cavity quantum electronic dynamic…
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…
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…
