Unified theory of classical and quantum ergotropy
Michele Campisi·Aug 18, 2025
Quantifying the ergotropy (a.k.a. available energy), namely the maximal amount of energy that can be extracted from a thermally isolated system, is a central problem in quantum thermodynamics. Notably, the same problem has been long studied for class...

Quantum State Preparation by Improved MPS Method
Chao Wang, Peng Zhou, Xi-Ning Zhuang +4 more·Aug 18, 2025
Efficient encoding of classical information plays a fundamental role in numerous practical quantum algorithms. However, the preparation of an arbitrary amplitude-encoded state has been proven to be time-consuming, and its deployment on current noisy ...
Graybox characterization and calibration with finite-shot estimation on superconducting-qubit experiments
Poramet Pathumsoot, A. Chantasri, Michal Hajduvsek +1 more·Aug 18, 2025
Characterization and calibration of quantum devices are necessary steps to achieve fault-tolerant quantum computing. As quantum devices become more sophisticated, it is increasingly essential to rely not only on physics-based models, but also on pred...
