Quantum Speed Limit From Tighter Uncertainty Relation
Shrobona Bagchi, Abhay Srivastav, Arun Kumar Pati
The quantum speed limit provides a fundamental bound on how fast a quantum system can evolve between the initial and the final states under any physical operation. The celebrated M…
Entanglement Meter: Estimation of entanglement with single copy in Interferometer
Som Kanjilal, Vivek Pandey, Arun Kumar Pati
Efficient certification and quantification of high dimensional entanglement of composite systems are challenging both theoretically as well as experimentally. Here, we demonstrate…
No-masking theorem for observables
Swapnil Bhowmick, Abhay Srivastav, Arun Kumar Pati
The no-masking theorem for quantum information proves that it is impossible to encode an arbitrary input state into a larger bipartite entangled state such that the full informatio…
Stronger Quantum Speed Limit
Dimpi Thakuria, Arun Kumar Pati
The quantum speed limit provides fundamental bound on how fast a quantum system can evolve between the initial and the final states. For the unitary evolution, the celebrated Mande…
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…
