Absence of quantum Darwinism as a resource in secure quantum communication and computation
Bishal Kumar Das, Sourav Manna, Vaibhav Madhok
The emergence of classical world from underlying quantum mechanics is characterized by not only vanishing quantum correlations but also an unfolding of objectivity also known as qu…

Quantum-to-classical transition and the emergence of trajectory level Darwinism with measurements distributed in time: a path integral approach
Harsh Arora, Bishal Kumar Das, Baladitya Suri +1
We present a formulation for the emergence of classical dynamics in a quantum world using a path integral approach that incorporates continuous measurements. Our approach complemen…

Information acquisition, scrambling, and sensitivity to errors in quantum chaos
Sreeram PG, Abinash Sahu, Naga Dileep Varikuti +3
Signatures of chaos can be understood by studying quantum systems whose classical counterpart is chaotic. However, the concepts of integrability, non-integrability and chaos extend…
