Correlation Enhanced Autonomous Quantum Battery Charging via Structured Reservoirs
Achraf Khoudiri, Abderrahim El Allati, Youssef Khlifi +3
In this work, we investigate autonomous charging of a quantum battery coupled to a structured reservoir composed of two qubits, each locally coupled to its own bosonic thermal bath…
Fidelity-informed neural pulse compilation of a continuous family of quantum gates with uncertainty-margin analysis
Arash Fath Lipaei, Ebrahim Khaleghian, Gani Göral +3
We develop a fidelity-informed neural pulse-compilation framework for a continuous family of single-qubit gates on a three-qubit liquid-state nuclear magnetic resonance (NMR) proce…
Spin-1 quantum annealing with anisotropy-controlled intermediate-state pathways
M. Haider Akbar, Ãzgür E. MüstecaplıoÄlu
Quantum annealing offers a promising strategy for solving complex optimization problems by encoding the solution into the ground state of a problem Hamiltonian. While most implemen…
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…
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…
Optimizing quantum sensing networks via genetic algorithms and deep learning
Asghar Ullah, Ãzgür E. MüstecaplıoÄlu, 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…
