Quantum Many-Body Metrology of Rotation Sensing with Strong Interactions
Yong-Jun Baak, Uwe R. Fischer
We study the ultimate quantum limit of rotation sensing with a few strongly interacting bosons confined in a quasi-one-dimensional ring trap with two weak links. It is demonstrated…
Restoring Heisenberg scaling in time via autonomous quantum error correction
Hyukgun Kwon, Uwe R. Fischer, Seung-Woo Lee +1
We establish a sufficient condition under which autonomous quantum error correction (AutoQEC) can effectively restore Heisenberg scaling (HS) in quantum metrology. Specifically, we…
Transition probabilities for a Rydberg atom in the field of a gravitational wave
Uwe R. Fischer
The possibility of an atomic detection of gravitational waves on earth is considered. The combination of extremely high lifetimes and resulting small radiative transition probabili…
Self-consistent many-body metrology
Jae-Gyun Baak, Uwe R. Fischer
We investigate performing classical and quantum metrology and parameter estimation by using interacting trapped bosons, which we theoretically treat by a self-consistent many-body…
Petrov classification of analogue spacetimes
Sang-Shin Baak, Satadal Datta, Uwe R. Fischer
In an effort to invariantly characterize the conformal curvature structure of analogue spacetimes built from a nonrelativistic fluid background, we determine the Petrov type of a v…
Beneficial and detrimental entanglement for quantum battery charging
Ju-Yeon Gyhm, Uwe R. Fischer
We establish a general implementation-independent approach to assess the potential advantage of using highly entangled quantum states between the initial and final states of the ch…
