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…
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…
Generalised quantum speed limit for arbitrary time-continuous evolution
Dimpi Thakuria, Abhay Srivastav, Brij Mohan +2
The quantum speed limit describes how quickly a quantum system can evolve in time from an initial state to a final state under a given dynamics. Here, we derive a generalised quant…
Information Bleaching, No-Hiding Theorem and Indefinite Causal Order
Abhay Srivastav, Arun Kumar Pati
The information bleaching refers to any physical process that removes quantum information from the initial state of the physical system. The no-hiding theorem proves that if inform…
