Robust single-qubit gates by composite pulses in three-level systems
Zhi-Cheng Shi, Hai-Ning Wu, Li-Tuo Shen +3
Composite pulses are an efficient tool for robust quantum control. In this work, we derive the form of the composite pulse sequence to implement robust single-qubit gates in a thre…
Two-level systems with periodic -step driving fields: Exact dynamics and quantum state manipulations
Zhi-Cheng Shi, Ye-Hong Chen, Wei Qin +4
In this work, we derive exact solutions of a dynamical equation, which can represent all two-level Hermitian systems driven by periodic -step driving fields. For different physi…
Robust generation of logical qubit singlet states with reverse engineering and optimal control with spin qubits
Yi-Hao Kang, Zhi-Cheng Shi, Jie Song +1
A protocol is proposed to generate singlet states of three logical qubits constructed by pairs of spins. Single and multiple operations of logical qubits are studied for the constr…
Heralded atomic nonadiabatic holonomic quantum computation with Rydberg blockade
Yi-Hao Kang, Zhi-Cheng Shi, Jie Song +1
We propose a protocol to realize atomic nonadiabatic holonomic quantum computation (NHQC) with two computational atoms and an auxiliary atom. Dynamics of the system is analyzed in…
Effective discrimination of chiral molecules in a cavity
Yi-Hao Kang, Zhi-Cheng Shi, Jie Song +1
We present a scheme to realize precise discrimination of chiral molecules in a cavity. Assisted by additional laser pulses, cavity fields can evolve to different coherence states w…
Pulse reverse-engineering for strong field-matter interaction
Du Ran, Bin Zhang, Ye-Hong Chen +5
We propose a scheme to control the evolution of a two-level quantum system in the strong coupling regime based on the idea of reverse-engineering. A coherent control field is desig…
