Quantum metrology pursues the physical realization of higher‐precision measurements to
physical quantities than the classically achievable limit by exploiting quantum features, such …

We revisit the interaction of a first-quantized atomic system (consisting of two charged
quantum particles) with the quantum electromagnetic field, pointing out the subtleties related …

Quantum metrology aims to measure physical quantities based on fundamental quantum

The time-dependent full counting statistics of charge transport through an interacting
quantum junction is evaluated from its generating function, controllably computed with the …

We evaluate the fundamental performance of a fiber-optic gyroscope (FOG) design that is
enhanced by the injection of a quantum-optical squeezed vacuum. In the presence of fiber …

Spin cat states are promising candidates for quantum-enhanced measurement. Here, we
analytically show that the ultimate measurement precision of spin cat states approaches the …

We propose a scheme to realize high-precision quantum interferometry with entangled non-
Gaussian states by driving the system through quantum phase transitions. The beam …

Gyroscope for rotation sensing plays a key role in inertial navigation systems. Developing
more precise gyroscopes than the conventional ones bounded by the classical shot-noise …

Inspired by the recent work [Nature (London) 521, 336 (2015) 0028-0836
10.1038/nature14458], we propose a scheme to suppress the backaction-induced …

We investigate the classical and quantum metrology of performing parameter estimation with
interacting trapped bosons, which we theoretically treat by a self-consistent many-body …
