Relations between quantum metrology and criticality in general su(1, 1) systems
Rui Zhang, Wenkui Ding, Zhucheng Zhang +3
There is a prevalent effort to achieve quantum-enhanced metrology using criticality. However, the extent to which estimation precision is enhanced through criticality still needs f…
