Nonreciprocal Relaxation Acceleration
Xingyu Zhang, Yihan Ma, Yue Liu +5
The authors demonstrate that a transient nonreciprocal dissipative channel can dramatically speed up the relaxation of a two‑mode bosonic system toward a nonequilibrium steady stat…

Beyond Photon Shot Noise: Chemical Limits in Spectrophotometric Precision
Georg Engelhardt, Dahai He, JunYan Luo
In this work, we investigate precision limitations in spectrophotometry (i.e., spectroscopic concentration measurements) imposed by chemical processes of molecules. Using the recen…

Collective advantages in qubit reset: effect of coherent qubits
Yue Liu, Chenlong Huang, Xingyu Zhang +1
The Landauer principle sets a lower bound on the thermodynamic cost of qubit reset, which is only attainable for the quasistatic process. In this Letter, we explore the collective…
