Entanglement depth and ancilla efficiency in quantum channel estimation
Javid Naikoo
We study the role of ancillary entanglement in quantum channel parameter estimation and investigate the minimal ancilla dimension required to achieve the maximum Fisher information…
Optomechanically controlled response amplification for enhanced quantum sensing
Javid Naikoo
We show that strongly amplified dynamical responses in cavity optomechanical systems can be harnessed for enhanced quantum sensing. By tuning the optomechanical interaction to a re…
Precision assessment in non-Hermitian systems: a comparative study of three formalisms
Javid Naikoo, Ravindra W. Chhajlany, Jan Kołodyński +1
Quantifying measurement precision in quantum systems is vital for advancing quantum technologies such as sensing, communication, and computation. The quantum Fisher information (QF…
Enhanced quantum sensing with hybrid exceptional-diabolic singularities
Javid Naikoo, Ravindra W. Chhajlany, Adam Miranowicz
We report an enhanced sensitivity for detecting linear perturbations near hybrid (doubly degenerated) exceptional-diabolic (HED) singular points in a four mode bosonic system. The…
Multiparameter estimation perspective on non-Hermitian singularity-enhanced sensing
Javid Naikoo, Ravindra W. Chhajlany, Jan Kolodynski
Describing the evolution of quantum systems by means of non-Hermitian generators opens a new avenue to explore the dynamical properties naturally emerging in such a picture, e.g. o…
