Quantum speed of evolution of neutral mesons
Subhashish Banerjee, K. G. Paulson
We investigate the quantum-mechanical time-evolution speed limit for neutral and mesons, both single as well as correlated, within the framework of open quantum systems. Th…
Quantum speed limit for the creation and decay of quantum correlations
K. G Paulson, Subhashish Banerjee
We derive Margolus-Levitin and Mandelstamm-Tamm type bound on the quantum speed limit time for the creation and decay of quantum correlations by an amount in a quantum system evolv…
Quantum correlations and speed limit of central spin system
Devvrat Tiwari, K. G. Paulson, Subhashish Banerjee
In this article, we consider single, and two-qubit central spin systems interacting with spin baths and discuss their dynamical properties. We consider the cases of interacting and…
Phase covariant channel: Quantum speed limit of evolution
Riya Baruah, K. G. Paulson, Subhashish Banerjee
The quantum speed of evolution for the phase covariant map is investigated. This involves absorption, emission and dephasing processes. We consider the maps under various combinati…
Quantum speed limit time: role of coherence
K. G. Paulson, Subhashish Banerjee
The minimum evolution time between multi-qubit quantum states is estimated for non-Markovian quantum channels. We consider the maximally coherent pure and mixed states as well as m…
