Harnessing Floquet dynamics for selective metrology in few-qubit systems
Asghar Ullah, Hasan Mermer, Melih Özkurt +2
Periodically driven quantum systems can function as highly selective parameter filters. We demonstrate this capability in a finite-size, three-qubit system described by the transve…
Optimizing quantum sensing networks via genetic algorithms and deep learning
Asghar Ullah, Özgür E. Müstecaplıoğlu, Matteo G. A. Paris
We investigate the optimization of graph topologies for quantum sensing networks designed to estimate weak magnetic fields. The sensors are modeled as spin systems governed by a tr…
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…
Configuration-dependent precision in magnetometry and thermometry using multi-qubit quantum sensors
Asghar Ullah, Özgür E. Müstecaplıoğlu, Matteo G. A. Paris
We study the performance of quantum sensors composed of four qubits arranged in different geometries for magnetometry and thermometry. The qubits interact via the transverse-field…
Quantum metrology of a structured reservoir
Youssef Aiache, Asghar Ullah, Özgür E. Müstecaplıoğlu +1
Accurately characterizing the properties of structured reservoirs is a key challenge in quantum systems and is of great importance for advances in quantum metrology and sensing. In…
Single-qubit probes for temperature estimation in the presence of collective baths
Asghar Ullah, Marco Cattaneo, Özgür E. Müstecaplıoğlu
We study the performance of single-qubit probes for temperature estimation in the presence of collective baths. We consider a system of two qubits, each locally dissipating into it…
