State of the Art and Prospects of Structured Sensing Matrices in Compressed Sensing
Kezhi Li, Shuang Cong
Compressed sensing (CS) enables people to acquire the compressed measurements directly and recover sparse or compressible signals faithfully even when the sampling rate is much low…
A Convergent control strategy for quantum systems
Shuang Cong, Yuesheng Lou, Jianxiu Liu +1
In the interaction picture, a sufficient and necessary condition that guarantees the convergence of closed quantum control system is proposed in this paper. Theoretical derivation…
Optimized Dynamical Decoupling in Ξ-Type n-Level Quantum Systems
Linping Chan, Shuang Cong
In this paper, we first design a type of Bang-Bang (BB) operation group to reduce the phase decoherence in a Ξ-type n-level quantum system based on the dynamical decoupling mechani…
A Robust Compressive Quantum State Tomography Algorithm Using ADMM
Kezhi Li, Shuang Cong
The possible state space dimension increases exponentially with respect to the number of qubits. This feature makes the quantum state tomography expensive and impractical for ident…
Ultrafast Manipulation of a Double Quantum Dot via Lyapunov Control Method
Shuang Cong, Ming-yong Gao, Long-zhen Hu +3
For a double quantum dot (DQD) system, here we propose alternative ultrafast manipulate approach: Lyapunov control method, to transfer the state from R to L on the picosecond scale…
Operator Preparation and Characteristic Analysis of Open Quantum Systems Based on the Lyapunov Control Method
Jie Wen, Shuang Cong
The control laws based on quantum Lyapunov control method are designed to prepare operators for two level open quantum systems in this paper. A novel Lyapunov function is proposed…
