Family of Exact and Inexact Quantum Speed Limits for Completely Positive and Trace-Preserving Dynamics
Abhay Srivastav, Vivek Pandey, Brij Mohan +1
Traditional quantum speed limits formulated in density matrix space are generally unattainable for a wide class of dynamics and it is difficult to characterize the fastest possible…
Exact Quantum Speed Limits
Arun K. Pati, Brij Mohan, Sahil +1
The traditional quantum speed limits are not attainable for many physical processes, as they tend to be loose and fail to determine the exact time taken by quantum systems to evolv…
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…
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…
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…
Quantum Speed Limits for Observables
Brij Mohan, Arun Kumar Pati
In the Schr{ö}dinger picture, the state of a quantum system evolves in time and the quantum speed limit describes how fast the state of a quantum system evolves from an initial sta…
Quantum speed limits for information and coherence
Brij Mohan, Siddhartha Das, Arun Kumar Pati
The quantum speed limit indicates the maximal evolution speed of the quantum system. In this work, we determine speed limits on the informational measures, namely the von Neumann e…
Quantum information can remain without physical body in volatile form
Brij Mohan, Sohail, Chirag Srivastava +2
A deeply rooted view in classical and quantum information is that "information is physical", i.e., to store and process information, we need a physical body. Here we ask whether qu…
