Nonreciprocal photon bundle emission
Baijun Li, Jing-Xue Liu, Tian-Xiang Lu +3
Quantum squeezing, a cornerstone of quantum optics and photonics, has played a key role in achieving ultra-precision sensing and realizing nonreciprocal engineering. However, the n…
Entanglement-enhanced quantum metrology via alternating in-phase and quadrature modulation
Jihao Ma, Jiahao Huang, Chaohong Lee
Quantum metrology harnesses quantum entanglement to improve measurement precision beyond standard quantum limit. Although nonlinear interaction is essential for generating entangle…
On-Demand Microwave Single-Photon Source Based on Tantalum Thin Film
Ying Hu, Sheng-Yong Li, En-Qi Chen +4
Single-photon sources are crucial for quantum information technologies. Here, we demonstrate a microwave single-photon source fabricated using a tantalum-based thin film, whose fav…
Structure, Optimality, and Symmetry in Shadow Unitary Inversion
Guocheng Zhen, Yu-Ao Chen, Mingrui Jing +3
Reversing unitary operations is a key task in quantum computing and quantum control. In this work, we introduce and develop the framework of shadow unitary inversion, a relaxed var…
Inter-species topological phases via a dynamical gauge field
Zhoutao Lei, Linhu Li
We uncover a class of inter-species topological phases in a one-dimensional lattice, loaded with two species of non-identical particles interacting via a dynamical gauge field (DGF…
Emergent Continuous Time Crystal in Dissipative Quantum Spin System without Driving
Shu Yang, Zeqing Wang, Libin Fu +1
Time crystals are a nonequilibrium phase of matter that extend fundamental spontaneous symmetry breaking into the temporal dimension, typically requiring external driving for their…
