Sub-Bath Cooling in Bosonic Systems: Gaussian Constraints and Non-Gaussian Enhancements
Wen-Han Png, Xueyuan Hu, Valerio Scarani
Cooling quantum systems with finite resources is a central task in quantum technologies and has been extensively explored in discrete-variable settings. As continuous-variable (CV)…
The Petz recovery map for optical losses
Jinyan Chen, Minjeong Song, Jared Jia Xuan Chan +1
Optical systems are a main platform for quantum information processing. A main challenge is information loss due to scattering in unmonitored modes. These losses are modeled as sta…
Exact and approximate conditions of tabletop reversibility: when is Petz recovery cost-free?
Minjeong Song, Hyukjoon Kwon, Valerio Scarani
Channels that describe open quantum dynamics are inherently irreversible: it is impossible to undo their effect completely, but one can study partial recovery of the…
Thermalization of finite complexity and its application to heat bath algorithmic cooling
Xueyuan Hu, Valerio Scarani
We introduce a class of thermal operations based on the collision model, where the system sequentially interacts with uncorrelated bath molecules via energy-preserving unitaries. T…
Petz recovery maps of single-qubit decoherence channels in an ion trap quantum processor
Wen-Han Png, Valerio Scarani
The Petz recovery map provides a near-optimal reversal of quantum noise, yet proposals for its implementation are only recent. We propose a physical realization of the exact state-…
