Journey in quantum metrology and sensing from foundations to applications: a review
Priya Ghosh, Tanoy Kanti Konar, Debraj Rakshit +2
We present a review on quantum metrology and sensing, from its foundations to current applications. Highlights of the review include consideration of both frequentist and Bayesian…
Recognizing critical lines via entanglement in non-Hermitian systems
Keshav Das Agarwal, Tanoy Kanti Konar, Leela Ganesh Chandra Lakkaraju +1
The non-Hermitian model exhibits counterintuitive phenomena that are not observed in the Hermitian counterparts. To probe the competition between non-Hermitian and Hermitian intera…
Hierarchies among genuine multipartite entangling capabilities of quantum gates
Mrinmoy Samanta, Sudipta Mondal, Samir Kumar Hazra +1
We classify quantum gates according to their capability to generate genuine multipartite entanglement (GME), using a hierarchy based on multipartite separable states. In particular…
Quantum sensing with ultracold simulators in lattice and ensemble systems: a review
Keshav Das Agarwal, Sayan Mondal, Ayan Sahoo +3
Sensing of parameters is an important aspect in all disciplines, with applications ranging from fundamental science to medicine. Quantum sensing and metrology is an emerging field…
Quantifying the particle aspect of quantum systems
Sreetama Das, Indranil Chakrabarty, Arun Kumar Pati +2
The possibility of a quantum system to exhibit properties that are akin to both the classically held notions of being a particle and a wave, is one of the most intriguing aspects o…
