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…
Enhancement of non-Markovianity due to environment-induced indirect interaction
Asif Zaman, Muhammad Faryad, Adam Zaman Chaudhry
Non-Markovian effects are often significant when the system-environment coupling is not weak. Indeed, we find that the non-Markovianity is negligible for a single two-level system…
Sensing high-frequency ac fields via a two-qubit sensor
Rizwan Abbas, Ali Raza Mirza, Adam Zaman Chaudhry
Quantum sensors allow us to measure weak oscillating fields with incredible precision. One common approach is to use the time evolution of a single two-level system (or a qubit) in…
Effect of repeated projective measurements on a two-qubit system undergoing dephasing
Hammas Hussain Ali, Muhammad Abdullah Ijaz, Fariha Hassan +2
The entanglement dynamics of an exactly solvable, pure dephasing model are studied. Repeated projective measurements are performed on the two-qubit system. Due to the system-enviro…
Improving the estimation of the environment parameters via a two-qubit scheme
Ali Raza Mirza, Adam Zaman Chaudhry
We demonstrate how using two qubits can drastically improve the estimation of environment parameters as compared to using only a single qubit. The two qubits are coupled to a commo…
The role of initial system-environment correlations with a spin environment
Ali Raza Mirza, Mah Noor Jamil, Adam Zaman Chaudhry
Open quantum systems are a subject of immense interest as their understanding is crucial in the implementation of modern quantum technologies. In the study of their dynamics, the r…
