Fundamental speed limits on entanglement dynamics of bipartite quantum systems
Vivek Pandey, Swapnil Bhowmick, Brij Mohan +2
The speed limits on entanglement are defined as the maximal rate at which entanglement can be generated or degraded in a physical process. We derive the speed limits on entanglemen…
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…
Towards Necessary and sufficient state condition for violation of a multi-settings Bell inequality
Swapnil Bhowmick, Som Kanjilal, A. K. Pan +1
High dimensional quantum entanglement and the advancements in their experimental realization provide a playground for fundamental research and eventually lead to quantum technologi…
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…
