Schr{ö}dinger cat state formation in small bosonic Josephson junctions at finite temperatures and dissipation
D V Tsarev, D V Ansimov, S A Podoshvedov +1
In this work, we consider the feasibility of Schr{ö}dinger cat (SC) and states formation by a convenient bosonic Josephson junction (BJJ) system in two-mode approximation.…

Quantum sensor network metrology with bright solitons
Dmitriy Tsarev, Stepan Osipov, Ray-Kuang Lee +2
We consider multiparameter quantum metrology problem with bright soliton networks in the presence of weak losses. We introduce General Heisenberg Limit (GHL) $Ï_{\boldsymbolÏ}=1/…
