Conditional entropy and information of quantum processes
Siddhartha Das, Kaumudibikash Goswami, Vivek Pandey
What would be a reasonable definition of the conditional entropy of bipartite quantum processes, and what novel insight would it provide? We develop this notion using four informat…
Effect of measurements on quantum speed limit
Abhay Srivastav, Vivek Pandey, Arun K Pati
Given the initial and final states of a quantum system, the speed of transportation of state vector in the projective Hilbert space governs the quantum speed limit. Here, we ask th…
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…
Fundamental limitations on the recoverability of quantum processes
Sohail, Vivek Pandey, Uttam Singh +1
Quantum information processing and computing tasks can be understood as quantum networks, comprising quantum states and channels and possible physical transformations on them. It i…
