Macroscopic Spin GHZ States with a Levitated Ferromagnet
Xueqi Ni, Zhixing Zou, Ping Koy Lam +2
The generation of macroscopic quantum states can drive both fundamental physics and quantum technologies. This work proposes a top-down approach to the generation of macroscopic sp…
The Quantum Kicked Rotor: A Paradigm of Quantum Chaos. Foundational aspects and new perspectives
Giuliano Benenti, Giulio Casati, Jiangbin Gong +1
The kicked rotor provides a simple yet powerful model for introducing many of the central concepts of classical and quantum chaos. Despite its apparent simplicity, it exhibits rich…
Cell-Dependent Criticality for Quantum Metrology
Zhoutao Lei, Jihao Ma, Yun Chen +2
Exploiting enhanced sensitivity of a system in the vicinity of a phase transition boundary, critical quantum metrology to date still suffers from gap-closure related bottleneck eff…
Microscopic theory of a precessing ferromagnet for ultrasensitive magnetometry
Xueqi Ni, Zhixing Zou, Ruvi Lecamwasam +5
Levitated systems have great potential in quantum sensing and exploring quantum effects at the macroscopic scale. Of particular interest are recent works suggesting that a levitate…
