We suggest a method to improve quantum correlations in cavity magnomechanics, through
the use of a coherent feedback loop and magnon squeezing. The entanglement of three …

The precision of quantum sensing could be improved by exploiting quantum phase
transitions, where the physical quantity tends to diverge when the system approaches the …

The Bures metric is a natural choice in measuring the distance of density operators
representing states in quantum mechanics. In the past few years a random matrix ensemble …

Nonclassicality is a key ingredient for quantum enhanced technologies and experiments
involving macroscopic quantum coherence. Considering various exactly solvable quantum …

Motion along semi-infinite straight line in a potential that is a combination of positive
quadratic and inverse quadratic functions of the position is considered with the emphasis on …

We present a way of measuring with high precision the anharmonicity of a quantum
oscillator coupled to an optical field via radiation pressure. Our protocol uses a sequence of …

We address quantitatively the relationship between the nonlinearity of a mechanical
resonator and the nonclassicality of its ground state. In particular, we analyze the …

A novel reconfigurable Microwave Photonics (MWP) mixer is presented in this paper, which
can be configured to work as a frequency hopper, ASK modulator and phase shifter. This …

The nonlinearity of a mechanical oscillator may lead to the generation of the macroscopic
quantum states, which are useful for precision measurement. Measuring the nonlinearity of a …
