Probing quantum phase transition via quantum speed limit
M Suman, S. Aravinda, Ranjan Modak
Quantum speed limit (QSL) is the lower bound on the time required for a state to evolve to a desired final state under a given Hamiltonian evolution. Three well-known QSLs exist Ma…
Quest for optimal quantum resetting: protocols for a particle on a chain
Pallabi Chatterjee, S. Aravinda, Ranjan Modak
In the classical context, it is well known that, sometimes, if the search does not find its target, it is better to start the process anew again, known as resetting. The quantum co…
Ergodic and mixing quantum channels: From two-qubit to many-body quantum systems
S. Aravinda, Shilpak Banerjee, Ranjan Modak
The development of classical ergodic theory has had a significant impact in the areas of mathematics, physics, and, in general, applied sciences. The quantum ergodic theory of Hami…
Non-Hermitian description of sharp quantum resetting
Ranjan Modak, S. Aravinda
We study a non-interacting quantum particle, moving on a one-dimensional lattice, which is subjected to repetitive measurements. We investigate the consequence when such motion is…
Complexity growth for one-dimensional free-fermionic lattice models
S. Aravinda, Ranjan Modak
Complexity plays a very important part in quantum computing and simulation where it acts as a measure of the minimal number of gates that are required to implement a unitary circui…
