Transit Noise in Spin Squeezing Experiments with Coated Rubidium Vapor Cell
Yujie Ji, Peiying Li, Yanhong Xiao +2
Spin squeezing can suppress quantum projection noise via interparticle entanglement, therefore enabling measurement sensitivities beyond the standard quantum limit. In practice, ho…
Enhancing collective spin squeezing via one-axis twisting echo control of individual atoms
Zhiwei Hu, Youwei Zhang, Junlei Duan +2
Spin squeezing generated via inter-atom entanglement in multilevel atomic ensembles provides a powerful resource for quantum-enhanced metrology. Existing schemes that harness inter…
Cooperative squeezing of internal and collective spins in an atomic ensemble
Youwei Zhang, Shenchao Jin, Junlei Duan +4
Creating highly spin-squeezed states for quantum metrology surpassing the standard quantum limit is a topic of great interest. Spin squeezing has been achieved by either entangling…
Continuous field tracking with machine learning and steady state spin squeezing
Junlei Duan, Zhiwei Hu, Xingda Lu +4
Entanglement plays a crucial role in proposals for quantum metrology, yet demonstrating quantum enhancement in sensing with sustained spin entanglement remains a challenging endeav…
Concurrent spin squeezing and light squeezing in an atomic ensemble
Shenchao Jin, Junlei Duan, Youwei Zhang +7
Squeezed spin states and squeezed light are both key resources for quantum metrology and quantum information science, but have been separately investigated in experiments so far. S…
Retrodiction beyond the Heisenberg uncertainty relation
Han Bao, Shenchao Jin, Junlei Duan +4
In quantum mechanics, the Heisenberg uncertainty relation presents an ultimate limit to the precision by which one can predict the outcome of position and momentum measurements on…
Measurements with prediction and retrodiction on the collective spin of 10^{11} atoms beat the standard quantum limit
Han Bao, Junlei Duan, Xingda Lu +10
Quantum probes using uncorrelated particles give a limit on the measurement sensitivity referred to as the standard quantum limit (SQL). The SQL, however, can be overcome by ex…
