Predicting topological quantum phase transition from dynamics via multisite entanglement
Leela Ganesh Chandra Lakkaraju, Sudip Kumar Haldar, Aditi Sen De
An exactly solvable Kitaev model in a two-dimensional square lattice exhibits a topological quantum phase transition which is different from the symmetry-breaking transition at zer…
Detecting exceptional points through dynamics in non-Hermitian systems
Keshav Das Agarwal, Tanoy Kanti Konar, Leela Ganesh Chandra Lakkaraju +1
Non-Hermitian rotation-time reversal (RT)-symmetric spin models possess two distinct phases, the unbroken phase in which the entire spectrum is real and the broken phase which cont…
Sequential Reattempt of Telecloning
Sudipta Das, Pritam Halder, Ratul Banerjee +1
The task of a telecloning protocol is to send an arbitrary qubit possessed by a sender to multiple receivers. Instead of performing Bell measurement at the sender's node, if one ap…
Refrigeration via purification through repeated measurements
Tanoy Kanti Konar, Srijon Ghosh, Aditi Sen De
We design a measurement-based quantum refrigerator with an arbitrary number of qubits situated in a one-dimensional array that interact through variable-range XY interactions. The…
Quantum battery with non-Hermitian charging
Tanoy Kanti Konar, Leela Ganesh Chandra Lakkaraju, Aditi Sen De
We propose a design of a quantum battery exploiting the non-Hermitian Hamiltonian as a charger. In particular, starting with the ground or the thermal state of the interacting (non…
