Engineering a Quantum Thermal Diode with Floquet Driving
Aqsa Rehman, M. Tahir Naseem, Adam Zaman Chaudhry
The paper proposes a quantum thermal diode built from two Ising‑coupled qubits whose heat flow can be strongly rectified using Floquet (periodic) driving, and derives a Floquet‑LGK…
Reservoir-Engineered Mechanical Cat States with a Driven Qubit
M. Tahir Naseem
Macroscopic quantum superpositions, such as mechanical Schrödinger cat states, are central to emerging quantum technologies in sensing and bosonic error-correcting codes. We propo…
Quantum thermal rectification via state-dependent two-photon dissipation
M. Tahir Naseem
Controlling heat flow at the quantum level is essential for the development of next-generation thermal devices. We investigate thermal rectification in a quantum harmonic oscillato…
Optimal strategies for transient and equilibrium quantum thermometry using Gaussian and non-Gaussian probes
Asghar Ullah, M. Tahir Naseem, Ãzgür E. MüstecaplıoÄlu
We study temperature estimation using quantum probes, including single-mode initial states and two-mode states generated via stimulated parametric down-conversion in a nonlinear cr…
Macroscopic distant magnon-mode entanglement via a squeezed drive
Kamran Ullah, Muhammad Tahir Naseem, Ãzgür E. MüstecaplıoÄlu
The generation of robust entanglement in quantum system arrays is a crucial aspect of the realization of efficient quantum information processing. Recently, the field of quantum ma…
Mixing thermal coherent states for precision and range enhancement in quantum thermometry
Asghar Ullah, M. Tahir Naseem, Ãzgür E. MüstecaplıoÄlu
The unavoidable interaction between thermal environments and quantum systems typically leads to the degradation of quantum coherence, which can be fought against by reservoir engin…
