Jaynes-Cummings dynamics in strong coupling for many-interacting-qubit quantum Rabi models
Roberto Grimaudo, Sagnik Chakraborty, Rosario Lo Franco +1
The present work focuses on the strong/weak interaction of many-body spin-systems with a cavity mode. It introduces the necessity of redefining the physical conditions determining…
Intrinsic Hamiltonian of Mean Force and Strong-Coupling Quantum Thermodynamics
Ignacio González, Sagnik Chakraborty, Ãngel Rivas
We present a universal thermodynamic framework for quantum systems that may be strongly coupled to thermal environments. Unlike previous approaches, our method enables a clear defi…
Efficient Estimation of Multiple Temperatures via a Collisional Model
Srijon Ghosh, Sagnik Chakraborty, Rosario Lo Franco
We present a quantum thermometric protocol for the estimation of multiple temperatures within the collisional model framework. Employing the formalism of multiparameter quantum met…
Quantum metrology using quantum combs and tensor network formalism
Stanislaw Kurdzialek, Piotr Dulian, Joanna Majsak +2
We develop an efficient algorithm for determining optimal adaptive quantum estimation protocols with arbitrary quantum control operations between subsequent uses of a probed channe…
