Principle of least action for quasi-adiabatic state transfers with dissipation
Si Luo, Yinan Fang, Yingdan Wang +1
We discuss a general formalism to optimize quasi-adiabatic state-transfer protocols, where high fidelity is achieved by maintaining the system in a dark subspace protected from the…
Strong mechanical squeezing in an unresolved-sideband optomechanical system
Rong Zhang, Yinan Fang, Yang-Yang Wang +2
We study how strong mechanical squeezing (beyond 3 dB) can be achieved through reservoir engineering in an optomechanical system which is far from the resolved-sideband regime. In…
Quantum sensing enhanced by adaptive periodic quantum control
Yi-Nan Fang, Xing Xiao, Chang-Pu Sun +2
Using a single quantum probe to sense other quantum objects offers distinct advantages but suffers from some limitations that may degrade the sensing precision severely, especially…
Quantifying Spontaneously Symmetry Breaking of Quantum Many-body Systems
G. H. Dong, Y. N. Fang, C. P. Sun
Spontaneous symmetry breaking is related to the appearance of emergent phenomena, while a non-vanishing order parameter has been viewed as the sign of turning into such symmetry br…
Quantification of Symmetry
Y. N. Fang, G. H. Dong, D. L. Zhou +1
Symmetry is conventionally described in a contrariety manner that the system is either completely symmetric or completely asymmetric. Using group theoretical approach to overcome t…
