Finite-Size Effects in Quantum Metrology at Strong Coupling: Microscopic vs Phenomenological Approaches
Ali Pedram, Ãzgür E. MüstecaplıoÄlu
We study the ultimate precision limits of a spin chain, strongly coupled to a heat bath, for measuring a general parameter and report the results for specific cases of magnetometry…
Nonlocality enhanced precision in quantum polarimetry via entangled photons
Ali Pedram, Vira R. Besaga, Frank Setzpfandt +1
A nonlocal quantum approach is presented to polarimetry, leveraging the phenomenon of entanglement in photon pairs to enhance the precision in sample property determination. By emp…
Quantum Estimation of the Stokes Vector Rotation for a General Polarimetric Transformation
Ali Pedram, Vira R. Besaga, Lea Gassab +2
Classical polarimetry is a well-established discipline with diverse applications across different branches of science. The burgeoning interest in leveraging quantum resources to ac…
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…
