Two-Tooth Bosonic Quantum Comb for Temporal-Correlation Sensing
Shaojiang Zhu · Xinyuan You · Alexander Romanenko · Anna Grassellino
Abstract
Author(s): Shaojiang Zhu, Xinyuan You, Alexander Romanenko, and Anna Grassellino<br/><p>We characterize the causal structure of coherence transport in open bosonic systems using a two-tooth quantum comb. We show that, by mapping sequential interactions between a structured bosonic absorber and a long-lived coherent probe onto a process-tensor description, the probe functions as a tempo…</p><br/>[Phys.
