Measurement-based Multipartite Entanglement Inflation
Pritam Halder, Shiladitya Mal, Aditi Sen De
Generating entanglement between more parties is one of the central tasks and challenges in the backdrop of building quantum technologies. Here we propose a measurement-based protoc…
Designing Robust Quantum Refrigerators in Disordered Spin Models
Tanoy Kanti Konar, Srijon Ghosh, Amit Kumar Pal +1
We explore a small quantum refrigerator in which the working substance is made of paradigmatic nearest-neighbor quantum spin models, the XYZ and the XY model with Dzyaloshinskii-Mo…
Detection of unbroken phase of non-Hermitian system via Hermitian factorization surface
Leela Ganesh Chandra Lakkaraju, Aditi Sen De
In the traditional quantum theory, one-dimensional quantum spin models possess a factorization surface where the ground states are fully separable having vanishing bipartite as wel…
Efficient nonlinear witnessing of non-absolutely separable states with lossy detectors
Ayan Patra, Shiladitya Mal, Aditi Sen De
Entangled states are undoubtedly an integral part of various quantum information processing tasks. On the other hand, absolutely separable states which cannot be made entangled und…
Dimensional enhancements in a quantum battery with imperfections
Srijon Ghosh, Aditi Sen De
Power storage devices are shown to increase their efficiency if they are designed by using quantum systems. We show that the average power output of a quantum battery based on a qu…
