Non-reciprocity and quantum correlations of light transport in hot atoms via reservoir engineering
Xingda Lu, Wanxia Cao, Wei Yi +2
The breaking of reciprocity is a topic of great interest in fundamental physics and optical information processing applications. We demonstrate non-reciprocal light transport in a…
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…
Entanglement-Enhanced Optical Atomic Clock
Edwin Pedrozo-Peñafiel, Simone Colombo, Chi Shu +8
State-of-the-art atomic clocks are based on the precise detection of the energy difference between two atomic levels, measured as a quantum phase accumulated in a given time interv…
Quantum correlations near the exceptional point
Wanxia Cao, Xingda Lu, Xin Meng +3
Recent advances in non-Hermitian physical systems have led to numerous novel optical phenomena and applications. However, most realizations are limited to classical systems and qua…
Near-Unitary Spin Squeezing in Yb
Boris Braverman, Akio Kawasaki, Edwin Pedrozo-Peñafiel +9
Spin squeezing can improve atomic precision measurements beyond the standard quantum limit (SQL), and unitary spin squeezing is essential for improving atomic clocks. We report sub…
Entangling and squeezing atoms by weak measurement
Mingfeng Wang, Weizhi Qu, Han Bao +2
A weak measurement approach is proposed to entangle and squeeze atoms. We show that even for very small coupling strength between light and atoms, one can achieve large squeezing u…
