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…
Bidirectional and passive optical field to microwave field quantum converter with high bandwidth

The conversion between microwave photons and optical photons with quantum coherence is important for quantum communication and computation. In this paper, we report a proposal usin…
Observation of critical phenomena in parity-time-symmetric quantum dynamics
Lei Xiao, Kunkun Wang, Xiang Zhan +5
We experimentally simulate non-unitary quantum dynamics using a single-photon interferometric network and study the information flow between a parity-time (PT)-symmetric non-Hermit…

Wen-Zhao Zhang, Li-Bo Chen, Jiong Cheng +1
We propose a theoretical scheme to enhance the signal-to-noise ratio in ultrasensitive detection with the help of quantum correlation. By introducing the auxiliary oscillator and t…
Polaron picture of the two-photon quantum Rabi model
Lei Cong, Xi-Mei Sun, Maoxin Liu +2
We employ a polaron picture to investigate the properties of the two-photon quantum Rabi model (QRM), which describes a two-level or spin-half system coupled with a single bosonic…
Self-consistent tomography of temporally correlated errors

The error model of a quantum computer is essential for optimizing quantum algorithms to minimize the impact of errors using quantum error correction or error mitigation. Noise with…
Quench dynamics and zero-energy modes: the case of the Creutz model
R. Jafari, Henrik Johannesson, A. Langari +1
In most lattice models, the closing of a band gap typically occurs at high-symmetry points in the Brillouin zone. Differently, in the Creutz model describing a system of spinle…

Lei Xiao, Xingze Qiu, Kunkun Wang +6
Topological matter exhibits exotic properties yet phases characterized by large topological invariants are difficult to implement, despite rapid experimental progress. A promising…
