Anti-Zeno boost in an autonomous quantized-piston thermal machine
M. Tahir Naseem
Anti-Zeno enhancement of quantum heat machines has been established for working fluids driven by an external classical field, but whether the same quantum advantage survives when a…
Engineering a Quantum Thermal Diode with Floquet Driving
Aqsa Rehman, M. Tahir Naseem, Adam Zaman Chaudhry
Controlling heat flow in small quantum systems is a central goal of quantum thermodynamics and nanoscale transport. A key challenge is to achieve strong thermal rectification witho…
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 propos…
Optimal strategies for transient and equilibrium quantum thermometry using Gaussian and non-Gaussian probes
Asghar Ullah, M. Tahir Naseem, Özgür E. Müstecaplıoğlu
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…
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…
Quantum thermometry with an optomechanical system
Asghar Ullah, Ali Pedram, M. Tahir Naseem +1
We present a quantum thermometry method utilizing an optomechanical system composed of an optical field coupled to a mechanical resonator for measuring the unknown temperature of a…
