Exploiting potentialities for space-based quantum communication network: downlink quantum key distribution modelling and scheduling analysis
Xingyu Wang, Chen Dong, Jiahua Wei +5
With the goal of a space-based quantum network is to have satellites distribute keys between any nodes on the ground, we consider an evolved quantum network from a near-term form,…
A new scheme for probabilistic teleportation and its potential applications
Jiahua Wei, Hong-Yi Dai, Ming Zhang
We propose a novel scheme for probabilistic teleportation when the information of the partially entangled state is only available for the sender. This is in contrast with the fact…
Trajectory-constrained optimal local time-continuous waveform controls for state transitions in -level quantum systems
Ming Zhang, Jia-Hua Wei, Weiwei Zhou +3
Based on a parametrization of pure quantum states we explicitly construct a sequence of (at most) local time-continuous waveform controls to achieve a specified state transi…
Manipulating quantum information on the controllable systems or subspaces
Ming Zhang, Zairong Xi, Jia-Hua Wei
In this paper, we explore how to constructively manipulate qubits by rotating Bloch spheres. It is revealed that three-rotation and one-rotation Hamiltonian controls can be constru…
