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…
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…
Duality between imperfect resources and measurements for propagating entanglement in networks
Sudipta Mondal, Pritam Halder, Aditi Sen De
We propose a measurement-based entanglement propagation strategy for networks in which all nodes except two are initially occupied by a suitably chosen single-qubit system and the…
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…
Framework of dynamical transitions from long-range to short-range quantum systems
Leela Ganesh Chandra Lakkaraju, Srijon Ghosh, Debasis Sadhukhan +1
A quantum many-body system undergoes phase transitions of distinct species with variations of local and global parameters. We propose a framework in which a dynamical quantity can…
Polynomial representation for multipartite entanglement of resonating valence bond ladders
Ajit Iqbal Singh, Aditi Sen De, Ujjwal Sen
A resonating valence bond (RVB) state of a lattice of quantum systems is a potential resource for quantum computing and communicating devices. It is a superposition of singlet, i.e…
