Optimized adiabatic-impulse protocol preserving Kibble-Zurek scaling with attenuated anti-Kibble-Zurek behavior
Han-Chuan Kou, Zhi-Han Zhang, Xin-Hui Wu +3
We propose an optimized adiabatic-impulse (OAI) protocol that substantially reduces the evolution time for crossing a quantum phase transition while preserving Kibble-Zurek (KZ) sc…
Complementary Collective Spin Descriptions of Superradiant Ramsey Spectroscopy
Ke-Xin Gao, Yuan Zhang, Shi-Lei Su +3
A recent experiment demonstrated delayed superradiance from strontium-88 atoms, which are coupled to a longitudinal mode of a cavity while being excited by laser pulses propagating…
Using PT-symmetric Qubits to Break the Tradeoff Between Fidelity and the Degree of Quantum Entanglement
B. -B. Liu, Shi-Lei Su, Y. -L. Zuo +4
A noteworthy discovery is that the minimal evolution time is smaller for parity-time () symmetric systems compared to Hermitian setups. Moreover, there is a significa…
Exact Numerical Solution of Stochastic Master Equations for Conditional Spin Squeezing
ZhiQing Zhang, Yuan Zhang, HaiZhong Guo +3
Stochastic master equations are often used to describe conditional spin squeezing of atomic ensemble, but are limited so far to the systems with few atoms due to the exponentially…
Theoretical Study on Superradiant Raman Scattering with Rubidium Atoms in An Optical Cavity
Huihui Yu, Yuan Zhang, Gang Chen +1
Superradiant Raman scattering of Rubidium atoms has been explored in the experiment [Nature 484, 78 (2012)] to prove the concept of the superradiant laser, which attracts significa…
Stochastic Mean-field Theory for Conditional Spin Squeezing by Homodyne Probing of Atom-Cavity Photon Dressed States
ZhiQing Zhang, HaiZhong Guo, Lingrui Wang +4
Projective measurements of collective observables can be employed to herald the preparation of entangled states of quantum systems, and the resulting conditional dynamics is usuall…
