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. S…
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) $σ_{\boldsymbolχ}=1/N^…
Enhanced nonlinear quantum metrology with weakly coupled solitons and particle losses
Alexander Alodjants, Dmitriy Tsarev, The Vinh Ngo +1
The estimation of physical parameters with Heisenberg sensitivity and beyond is one of the crucial problems for current quantum metrology. However, unavoidable lossy effect is comm…
Superradiant phase transition in complex networks
Andrei Yu. Bazhenov, Dmitriy V. Tsarev, Alexander P. Alodjants
In this work we consider a superradiant phase transition problem for the Dicke-Ising model, which generalizes the Dicke and Ising models for annealed complex networks presuming spi…
Mesoscopic quantum superposition states of weakly-coupled matter-wave solitons
Dmitriy Tsarev, Alexander Alodjants, The Vinh Ngo +1
The Josephson junctions (JJs) are at the heart of modern quantum technologies and metrology. In this work we establish quantum features of an atomic soliton Josephson junction (SJJ…
Bose-Einstein condensate soliton qubit states for metrological applications
The Vinh Ngo, Dmitriy Tsarev, Ray-Kuang Lee +1
By utilizing Bose-Einstein condensate solitons, optically manipulated and trapped in a double-well potential, coupled through nonlinear Josephson effect, we propose novel quantum m…
Quantum metrology beyond Heisenberg limit with entangled matter wave solitons
D. V. Tsarev, S. M. Arakelian, You-Lin Chuang +2
By considering matter wave bright solitons from weakly coupled Bose-Einstein condensates trapped in a double-well potential, we study the formation of macroscopic non-classical sta…
