Unequal Coherent Ergotropy at Equal Interferometric Visibility and Energy in Quantum-Controlled Interferometers
Tonipe Anuradha, André H. A. Malavazi, Borhan Ahmadi +2
The ergotropy, or unitarily extractable work, of a quantum system naturally splits into incoherent and coherent contributions, respectively set by population inversion and coherenc…
Physical-Work Fluctuation Relations from Accessible Quantum Macrostates
Borhan Ahmadi
Jarzynski's equality recovers an equilibrium free-energy difference from nonequilibrium work trajectories, but its exponential average can converge very slowly because rare traject…
Finite-Particle Quantum Reduction of Thermodynamic Irreversibility
Borhan Ahmadi
Thermodynamics is useful because it lets us predict and control complex systems from a few accessible quantities when microscopic reconstruction is impractical. We ask whether this…
Thermodynamic Irreversibility from Inaccessible Endogenous Quantum Histories
Borhan Ahmadi
Microscopic unitary dynamics preserves all fine information, yet an isolated finite system can show a robust thermodynamic window in which the entropy associated with a restricted…
Finite-Time Optomechanical Cooling by Multi-Exceptional-Point Braiding
Borhan Ahmadi
Cooling a mechanical mode in finite time is a routing problem: excitation must reach a lossy mode before thermal noise rebuilds the population. Exceptional points are non-Hermitian…
Quantum Batteries as Work Sources for Phase-Locked Parametric Amplification
Borhan Ahmadi
Quantum batteries have been proposed as locally precharged work sources for superconducting quantum technologies, suggesting a route to reduce continuously supplied microwave drive…
Charging Quantum Batteries with Chiral Squeezing
Borhan Ahmadi, André H. A. Malavazi, Janine Splettstoesser +2
We propose a quantum-battery charger based on a driven bosonic Kitaev chain (BKC), where chiral squeezing converts passive input fluctuations into ordered, non-passive battery stat…
Quantum-Battery-Powered Geometric Landau-Zener Interferometry
Borhan Ahmadi
Classical microwave drives are usually treated as ideal phase-coherent work sources for superconducting-qubit control. What if such a drive is replaced by a finite quantum battery.…
Reservoir-Engineered Low-Threshold Quantum Energy Storage
Borhan Ahmadi, André H. A. Malavazi, Paweł Mazurek +2
Fast charging of quantum batteries requires amplification of the energy transferred to a storage mode without uncontrolled gain or phenomenological non-Hermitian dynamics. Inspired…
Charge-Preserving Operations in Quantum Batteries
André H. A. Malavazi, Borhan Ahmadi, Paweł Horodecki +1
Ergotropy provides a fundamental measure of the extractable work from a quantum system and, consequently, of the maximal useful energy, or charge, stored within it. Understanding h…
Harnessing Environmental Noise for Quantum Energy Storage
Borhan Ahmadi, Aravinth Balaji Ravichandran, Paweł Mazurek +2
Quantum hardware increasingly relies on energy reserves that can later be converted into useful work; yet, most battery-like proposals demand coherent drives or engineered non-equi…
Two-time weak measurement protocol for ergotropy protection in open quantum batteries
André H. A. Malavazi, Rishav Sagar, Borhan Ahmadi +1
Quantum batteries are emerging as highly efficient energy storage devices that can exceed classical performance limits. Although there have been significant advancements in control…
Super-Optimal Charging of Quantum Batteries via Reservoir Engineering
Borhan Ahmadi, Paweł Mazurek, Shabir Barzanjeh +1
Energy dissipation, typically considered an undesirable process, has recently been shown to be harnessed as a resource to optimize the performance of a quantum battery. Following t…

André H. A. Malavazi, Borhan Ahmadi, Paweł Mazurek +1
Navigating the intricacies of thermal management at the quantum scale is a challenge in the pursuit of advanced nanoscale technologies. To this extent, theoretical frameworks intro…
Nonreciprocal Quantum Batteries
Borhan Ahmadi, Paweł Mazurek, Paweł Horodecki +1
Nonreciprocity, arising from the breaking of time-reversal symmetry, has become a fundamental tool in diverse quantum technology applications. It enables directional flow of signal…
