Motional -phonon Bundle States of A Trapped Atom with Clock Transitions
Yuangang Deng, Tao Shi, Su Yi
Quantum manipulation of individual phonons could offer new resources for studying fundamental physics and creating an innovative platform in quantum information science. Here, we p…
Trapped Bose-Einstein Condensates with Attractive s-wave Interaction
Tao Shi, Junqiao Pan, Su Yi
Within the framework of the Gaussian-state theory, we show that the quantum many-body ground state of a trapped condensate with weakly attractive interaction is a single-mode squee…
Efficient generation of many-body entangled states by multilevel oscillations
Peng Xu, Su Yi, Wenxian Zhang
We generate high-fidelity massively entangled states in an antiferromagnetic spin-1 Bose-Einstein condensate (BEC) by utilizing multilevel oscillations. Combining the multilevel os…
Parity-Enhanced Quantum Optimal Measurements
Haijun Xing, Libin Fu, Su Yi
We find a large class of pure and mixed input states with which the phase estimation precision saturates the Cramer-Rao bound under the compound measurements of parity and particle…
