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)…

Drive-Through Quantum Gate: Non-Stop Entangling a Mobile Ion Qubit with a Stationary One
Ting Hsu, Wen-Han Png, Kuan-Ting Lin +2
Towards the scalable realization of a quantum computer, a quantum charge-coupled device (QCCD) based on ion shuttling has been considered a promising approach. However, the process…

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-…
