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…
Subgap modes in two-dimensional magnetic Josephson junctions
Yinan Fang, Seungju Han, Stefano Chesi +1
We consider two-dimensional superconductor/ferromagnet/superconductor junctions and investigate the subgap modes along the junction interface. The subgap modes exhibit characterist…
Recent advances in hole-spin qubits
Yinan Fang, Pericles Philippopoulos, Dimitrie Culcer +2
In recent years, hole-spin qubits based on semiconductor quantum dots have advanced at a rapid pace. We first review the main potential advantages of these hole-spin qubits with re…
Probing Kondo spin fluctuations with scanning tunneling microscopy and electron spin resonance
Yinan Fang, Stefano Chesi, Mahn-Soo Choi
We theoretically analyze a state-of-the-art experimental method based on a combination of electron spin resonance and scanning tunneling microscopy (ESR-STM), to directly probe the…
Superradiant-like dynamics by electron shuttling on a nuclear-spin island
Yi-Nan Fang, Ying-Dan Wang, Rosario Fazio +1
We investigate superradiant-like dynamics of the nuclear-spin bath in a single-electron quantum dot, by considering electrons cyclically shuttling on/off an isotopically enriched `…
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…
Entanglement of spin-orbit qubits induced by Coulomb interaction
Y. N. Fang, Yusuf Turek, J. Q. You +1
Spin-orbit qubit (SOQ) is the dressed spin by the orbital degree of freedom through a strong spin-orbit coupling. We show that Coulomb interaction between two electrons in quantum…
