Quantum Speed limit on the production of quantumness of observables
Divyansh Shrimali, Swapnil Bhowmick, Arun Kumar Pati
Non-classical features of quantum systems can degrade when subjected to environment and noise. Here, we ask a fundamental question: What is the minimum amount of time it takes for…
Stronger speed limit for observables: Tight bound for the capacity of entanglement, the modular Hamiltonian and the charging of a quantum battery
Divyansh Shrimali, Biswaranjan Panda, Arun Kumar Pati
How fast an observable can evolve in time is answered by so-called ``observable speed limit". Here, we prove a stronger version of the observable speed limit and show that the prev…
Capacity of Entanglement for Non-local Hamiltonian
Divyansh Shrimali, Swapnil Bhowmick, Vivek Pandey +1
The notion of capacity of entanglement is the quantum information theoretic counterpart of the heat capacity which is defined as the second cumulant of the entanglement spectrum. G…
Speed limits on correlations in bipartite quantum systems
Vivek Pandey, Divyansh Shrimali, Brij Mohan +2
Quantum speed limit is bound on the minimum time a quantum system requires to evolve from an initial state to final state under a given dynamical process. It sheds light on how fas…
