Coherence-Enhanced Spatial Quantum Thermometry
Asghar Ullah, Giovanni Scala, Luis L. Sánchez-Soto +1
Quantum thermometry has long promised sensitivities beyond classical limits, with recent paradigms highlighting quantum coherence as a primary driver of precision. While most studi…
Collective-dissipation-induced dark and metastable-like states for enhanced quantum battery performance
Achraf Khoudiri, Asghar Ullah, Abderrahim El Allati +1
We investigate the role of symmetry-protected dark states and metastable-like frozen states in the autonomous charging dynamics of open quantum batteries described by a transverse-…
Topological Engine Monitor: Persistent Homology-Based Fault Detection in Finite-Time Quantum Engines
Miraç Kerem Maden, Asghar Ullah, Baris Coskunuzer +1
The reliable operation of finite-time quantum heat engines is fundamentally limited by control imperfections that induce nonadiabatic phase accumulation and quantum friction, degra…
Squeezing- and non-Gaussianity-enhanced quantum thermometry and magnetometry via quadratic interactions in optomechanical-like systems
Asghar Ullah, Özgür E. Müstecaplıoğlu
Standard optomechanical sensors operating in the low-temperature regime often face fundamental precision limits imposed by vacuum fluctuations. Here, we demonstrate that moving bey…
