Improving the estimation of environment parameters via initial probe-environment correlations
Hamza Ather, Adam Zaman Chaudhry
Small, controllable quantum systems, known as quantum probes, have been proposed to estimate various parameters characterizing complex systems such as the environments of quantum s…
The quantum Zeno and anti-Zeno effects with driving fields in the weak and strong coupling regimes
Mehwish Majeed, Adam Zaman Chaudhry
Repeated measurements in quantum mechanics can freeze (the quantum Zeno effect) or enhance (the quantum anti-Zeno effect) the time-evolution of a quantum system. In this paper, we…
Impact of independent reservoirs on the quantum Zeno and anti-Zeno effects
Irfan Javed, Mohsin Raza, Adam Zaman Chaudhry
In this paper, we look into what happens to a quantum system under repeated measurements if it interacts with two independent reservoirs. In particular, we look at the behavior of…
A master equation incorporating the system-environment correlations present in the joint equilibrium state
Ali Raza Mirza, Muhammad Zia, Adam Zaman Chaudhry
We present a general master equation, correct to second order in the system-environment coupling strength, that takes into account the initial system-environment correlations. We a…
Continuous dynamical decoupling of spin chains: Inducing two-qubit interactions to generate perfect entanglement
Abdullah Irfan, Syed Furqan Abbas Hashmi, Syeda Neha Zaidi +3
Efficient control over entanglement in spin chains is useful for quantum information processing applications. In this paper, we propose the use of a combination of two different co…
